What does this PR try to resolve?

Fixes #15059
Fixes #15159

This provides an escape hatch --exclude-lockfilefor uncommon workflows
that don't verify (--no-verify is passed) the build with their unpublished packages
In effect, this takes the heuristic removed in #14815 and replaces it with a flag

When --exclude-lockfile is enabled,
cargo package will not verify the lock file if present,
nor will it generate a new one if absent.
Cargo.lock will not be included in the resulting tarball.

Together with --no-verify,
this flag decouples packaging from checking the registry index.
While this is useful for some non-normal workflows that requires
to assemble packages having unpublished dependencies.
It is recommended to use -Zpackage-workspace to package the entire
workspace, instead of opting out lockfile.

How should we test and review this PR?

The first commit was stolen from NoisyCoil@1a104b5 (credit to @NoisyCoil!)

The second added two failing cases we observed in #15059.

Mind cleaning up the commit history (reorder test first, squash test update), including updating commint message for new flag name?

Thanks for stealing, very much appreciated! (Especially the part where I don't have to come up with a better name for the flag ;-))

After dd698ff,
`cargo package --no-verify` at least fails in three different cases:

* An unpublished package depending on itself as a dev-dependency (cyclic self-referential dev-dependencies).
  * Can be resolved by removing the `version` field from the affected dev-dependency.
  * `-Zpackage-workspace` doesn't help with it.
* Existing `cargo package` has `--package <pkg>` specifying certain unpublished packages.
  * Can be resolved by specifying all unpublished packages in one `cargo` call.
  * `-Zpackage-workspace` also requires all dependency versions available in the target registry when calling, so doesn't help.
* `cargo package --no-verify` has been used as a kind of “plumbing commands” to create tarballs without considering dependency orders. The use cases include:
  * Preparing tarballs for other package managers.
  * Integrating into custom develop workflows for unpublished/internal crates.
  * Constructing custom/private registries.

This commit shows the former two cases.
When `--exclude-lockfile` is enabled,
`cargo package` will not verify the lock file if present,
nor will it generate a new one if absent.
Cargo.lock will not be included in the resulting tarball.

Together with `--no-verify`,
this flag decouples packaging from checking the registry index.

to assemble packages having unpublished dependencies.
It is recommended to use `-Zpackage-workspace` to package the entire

## Compatibility Notes

-   [Rust now raises an error for macro invocations inside the `#![crate_name]` attribute](rust-lang/rust#127581)
-   [Unstable fields are now always considered to be inhabited](rust-lang/rust#133889)
-   [Macro arguments of unary operators followed by open beginning ranges may now be matched differently](rust-lang/rust#134900)
-   [Make `Debug` impl of raw pointers print metadata if present](rust-lang/rust#135080)
-   [Warn against function pointers using unsupported ABI strings in dependencies](rust-lang/rust#135767)
-   [Associated types on `dyn` types are no longer deduplicated](rust-lang/rust#136458)
-   [Forbid attributes on `..` inside of struct patterns (`let Struct { #[attribute] .. }) =`](rust-lang/rust#136490)
-   [Make `ptr_cast_add_auto_to_object` lint into hard error](rust-lang/rust#136764)
-   Many `std::arch` intrinsics are now safe to call in some contexts, there may now be new `unused_unsafe` warnings in existing codebases.
-   [Limit `width` and `precision` formatting options to 16 bits on all targets](rust-lang/rust#136932)
-   [Turn order dependent trait objects future incompat warning into a hard error](rust-lang/rust#136968)
-   [Denote `ControlFlow` as `#[must_use]`](rust-lang/rust#137449)
-   [Windows: The standard library no longer links `advapi32`, except on win7.](rust-lang/rust#138233) Code such as C libraries that were relying on this assumption may need to explicitly link advapi32.
-   [Proc macros can no longer observe expanded `cfg(true)` attributes.](rust-lang/rust#138844)
-   [Start changing the internal representation of pasted tokens](rust-lang/rust#124141). Certain invalid declarative macros that were previously accepted in obscure circumstances are now correctly rejected by the compiler. Use of a `tt` fragment specifier can often fix these macros.
-   [Don't allow flattened format_args in const.](rust-lang/rust#139624)

Cargo
-----
- [Add terminal integration via ANSI OSC 9;4 sequences]
  (rust-lang/cargo#14615)
- [chore: bump openssl to v3]
  (rust-lang/cargo#15232)
- [feat(package): add --exclude-lockfile flag]
  (rust-lang/cargo#15234)

Compatibility Notes
-------------------
- [Rust now raises an error for macro invocations inside the
  `#![crate_name]` attribute]
  (rust-lang/rust#127581)
- [Unstable fields are now always considered to be inhabited]
  (rust-lang/rust#133889)
- [Macro arguments of unary operators followed by open beginning
  ranges may now be matched differently]
  (rust-lang/rust#134900)
- [Make `Debug` impl of raw pointers print metadata if present]
  (rust-lang/rust#135080)
- [Warn against function pointers using unsupported ABI strings in dependencies]
  (rust-lang/rust#135767)
- [Associated types on `dyn` types are no longer deduplicated]
  (rust-lang/rust#136458)
- [Forbid attributes on `..` inside of struct patterns (`let Struct
  { #[attribute] .. }) =`]
  (rust-lang/rust#136490)
- [Make `ptr_cast_add_auto_to_object` lint into hard error]
  (rust-lang/rust#136764)
- Many `std::arch` intrinsics are now safe to call in some contexts,
  there may now be new `unused_unsafe` warnings in existing codebases.
- [Limit `width` and `precision` formatting options to 16 bits on all targets]
  (rust-lang/rust#136932)
- [Turn order dependent trait objects future incompat warning into a hard error]
  (rust-lang/rust#136968)
- [Denote `ControlFlow` as `#[must_use]`]
  (rust-lang/rust#137449)
- [Windows: The standard library no longer links `advapi32`, except
  on win7.] (rust-lang/rust#138233)
  Code such as C libraries that were relying on this assumption
  may need to explicitly link advapi32.
- [Proc macros can no longer observe expanded `cfg
  (true)` attributes.](rust-lang/rust#138844)
- [Start changing the internal representation of pasted tokens]
  (rust-lang/rust#124141). Certain invalid
  declarative macros that were previously accepted in obscure
  circumstances are now correctly rejected by the compiler. Use of
  a `tt` fragment specifier can often fix these macros.
- [Don't allow flattened format_args in const.]
  (rust-lang/rust#139624)

Internal Changes
----------------

These changes do not affect any public interfaces of Rust, but they
represent significant improvements to the performance or internals
of rustc and related tools.

- [Update to LLVM 20]
