Support same_pkg_direct_rdeps in aquery (or post-analysis queries more generally)

[shahms]

Description of the feature request:

It's not currently possible to reasonably replicate the behavior of bazel print_action --nobuild --compile_one_dependency path/to/source_file.cc using bazel aquery. While print_action and --compile_one_dependency exist, this isn't a huge deal but as the latter is intended to be removed, it would be good to have a reasonable replacement.

Which category does this issue belong to?

Core

What underlying problem are you trying to solve with this feature?

Provide a suitable replacement for --compile_one_dependency before it goes away.

Which operating system are you running Bazel on?

Linux

What is the output of bazel info release?

release 6.5.0-7

If bazel info release returns development version or (@non-git), tell us how you built Bazel.

No response

What's the output of git remote get-url origin; git rev-parse HEAD ?

Have you found anything relevant by searching the web?

Primarily just the comment indicating that --compile_one_dependency is going to be removed
#13419 (comment)

Any other information, logs, or outputs that you want to share?

No response

Mai, I remember you looked into this general domain internally at Google in ~2022. Can you please share your thoughts?

Fyi @comius, the author of the linked comment.

I cannot remember the blockers for allowing same_pkg_direct_rdeps to be available for aquery. But I remember that aquery with same_pkg_direct_rdeps were not enough to exactly replace what print_action --compile_one_dependency does. For example print_action can actually perform a build on the selected target while aquery does not. Also --compile_one_dependency can unwrap filegroup chains to get to a meaningful rdep of the give file while same_pkg_direct_rdeps does not do that. Maybe siblings can be a better fit in this case but it is also not available for aquery IIRC.

Yeah, the error from attempting to use same_pkg_direct_rdeps from aquery specifically mentions the use of siblings as the underlying cause
