This provides the ability to run merge_target_files without the end goal
of a target files zip. This is useful for users that only want the IMAGES
folder, for example.
Bug: 130304869
Test: python -m unittest test_merge_target_files

About half of the testcases rely on external tools (i.e. the ones in
`otatools.zip`, which are external to releasetools module, but still
built by Android). It's WAI as releasetools scripts are mostly for
gluing purpose.
However, the current support in Soong doesn't allow packing the helper
modules as part of the built releasetools_test. This CL adds a decorator
that allows declaring external dependencies in testcases, which will be
skipped while running in presubmit. It doesn't affect local invocation
of `atest releasetools_test`.
Fixes: 112080715
Test: `atest releasetools_test`
Test: TreeHugger; check that releasetools_test is invoked (and test
passes).
