[7.2.0] Make bazel mod tidy work with include()

[bazel-io]

We now generate fixup commands targeting include()d segments in addition to the root MODULE.bazel file itself. Fixup commands are grouped by file, and then passed to Buildozer using -f - (i.e. multiple commands for multiple files, passed in using stdin).

• For repos to add, we find the first usage with the correct prod/dev type and add them there.
• For repos to remove, we remove them from whichever usage had them.
• At the end, all module files and included segments are formatted.

Fixes #22063

Closes #22455.

huh, I might need some help here. @fmeum @meteorcloudy For some reason, the test //src/test/py/bazel:mod_command_test hangs indefinitely on Windows -- very consistently, too.

The test methods testModTidy* are where things go wrong; it looks like the call to bazel mod tidy just hangs forever. But the weird thing is that this PR is a clean cherry-pick; the same code works just fine on Windows at HEAD (see #22455; also verified with a Windows VM).

I can't quite see the output of the inner Bazels easily; --sandbox_debug also doesn't seem to do anything (understandable as AFAIK there's no sandbox on Windows anyway). Any advice?

Wild guess: We may be hitting a bug that was fixed by b3f5c62 at HEAD just three days ago. I'll verify this.
