Add --experimental_retain_test_configuration_across_testonly

Action conflicts continue to be an issue when non-test (e.g. genquery, filegroup, etc.) depends on cc_test.

This flag averts the issue by skipping trimming when testonly is true (and testonly must already be true for a non-test target to depend on a test). This does mean you only get the performance gain for non-testonly targets; however, this is still sufficiently substantial.

The expected progression of this flag is False -(soon-after-release)-> True -(eventually-after-depot-migration)-> False -> gone/deprecated.

Alternative name was experimental_trim_test_configuration_ignores_testonly with reversed behavior (flag True is pre-CL behavior) which would have incurred a flag progression of False (default, causing immediate behavior change on release) -(eventually-after-depot-migration)-> True -> gone/deprecated.
