build: add flag_alias definition for Starlarkification of python flags (#3450)

With this change, when user build with a native python flag,
`flag_alias` will point to the starlark version of the flag. Please see
design doc
[here](https://docs.google.com/document/d/1yOvi4hVV7Ja32ocwVb4lsEUnijftk8nilXPncYm-BH8/edit?tab=t.0#heading=h.qn3unswby87l)
for more details.

This feature should work as a no-op in the latest bazel 8.x and 7.x
releases.
