Add test_mainline_modules to the auto-gen test config(AndroidJUnitTest only).

To support parameterized mainline modules in Test Mapping, we plan to
add a new parameter called test_mainline_modules in build system to
auto-generate the test config based on the parameter.

For detailed information: go/test-mapping-mainline-gcl
(search for auto-generated pattern)

Bug: 155238134
Test: add "test_mainline_modules: [some.apk]" to TetheringTests,
and build the modules, confirm the parameterized option is added
in the test config.
