[7.1.0] Use execution info instead of hard-coded mnemonics for Java path mapping (#21461)

By removing Java rules from the hard-coded mnemonics allowlist for path
mapping, users can rely on `--modify_execution_info` to selectively
disable path mapping for them just like for Starlark actions.

This requires fixing two minor inconsistencies in how execution info is
populated for Java actions:
* In `JavaCompilationHelper`, `buildKeepingLast` is used instead of
`buildOrThrow` to prevent a crash when a target sets
`supports-path-mapping` via `tags`.
* In `JavaHeaderCompileAction`, `--experimental_inmemory_jdeps_files` no
longer causes all other execution info to be lost.

Fixes #21092

Closes #21093.
