Add the following build actions {BUILD_MODULES_IN_A_DIRECTORY,
BUILD_MODULES_IN_DIRECTORIES} in soong_ui config so the bash code version of
build commands (m, mm, mma, mmm, mmma) in build/make/envsetup.sh can be deprecated.
This is to allow up to date bug fixes on the build commands.
Bug: b/130049705
Test: Unit test cases
