Replace the current unit test runner DeviceJUnit4ClassRunner with JUnit4
and replace the (larger) dependency tradefed with the (smaller)
dependency junit.
This has no impact other than minimizing the unit test static_libs.

Teach check-flagged-apis to parse the parsed_flags protobuf generated by
aconfig.
Note: `m all_aconfig_declarations` generates a protobuf file that
contains all info about all flags.

Teach check-flagged-apis to extract flagged APIs from API signature files.
To keep things simple, only consider fields for now: support for classes
and methods will be added in a later CL.
Note: `m frameworks-base-api-current.txt` will generate an API signature
file that includes both the platform and mainline APIs.

Add a new CLI to verify that the build artifacts contain the right set
of @FlaggedApi APIs, based on the value of the corresponding aconfig
flag.
This CLI will act as an end-to-end test of Soong and metalava.
This CL only adds the project scaffolding; later CLs will add the
implementation.
