Render parsed source identifiers back to their canonical SourceOp form before
source policy evaluation. This lets Git subdir cleanup use the existing source
parser and avoids policy-specific Git parsing.
Add String methods for source identifiers and cover them with unit tests, plus
a client integration regression for canonical Git subdir policy matching.

(cherry picked from commit 8c994eb561a2646b35352e5663afecd225306214)
Add git.mtime=commit option that normalizes all file, symlink,
and directory mtimes in a git snapshot to the resolved commit
timestamp. This enables reproducible builds from git sources.
When SOURCE_DATE_EPOCH is set in the Dockerfile frontend, the
git context automatically uses commit-time mtimes. The URL
query parameter ?mtime=commit|checkout can override this.
New LLB attr (git.mtime) and capability (source.git.mtime) are
registered as experimental. Cache keys include the mtime policy
so that commit-time and checkout-time snapshots are distinct.

The `git checkout tree-ish -- pathspec` command run by buildkit to
populate the work tree defaults to overlay mode, so it won't delete objects
which exist in the work tree but don't exist in the tree-ish. It's not a
problem for ordinary file and directory objects because the work tree
starts out empty, but in the case where submodules are deleted or
renamed it will leave stale gitlink references in the index. The
subsequent `git submodule update ...` command will then fail with an
eror like 'No url found for submodule path ... in .gitmodules' as seen
in #4260.
Adding `--no-overlay` ensures that any deleted gitlink references are
removed from the index before the submodule update runs.

This is more flexible as from the user standpoint it might not
be easy to know if a version tag is annotated or not.
Downside of this change is that we can't create a cache key
automatically when checksum was set and no keep-git-dir as we
don't know which checksum is being used.

This fails in `gitSourceHandler` because it can't handle *both* SHA-1 and SHA-256 before Git 2.45 (see PR comments), and there's not a simple way to fix that without newer Git or larger refactoring.

Because subdir filter happened before the submodule update it
resulted in empty directory being filtered and submodule update
