instruction-padding: Remove solana-program dependency (#7436)

* instruction-padding: Remove solana-program dependency

#### Problem

The instruction-padding program still has an explicit dependency on
solana-program, but it isn't needed.

#### Summary of changes

Use the component crates instead. Some of the syscall consts aren't
available yet outside of solana-program, but it was easy to add a static
assertion for those.

* Add re-exports
