Create tradefed-core target for better atest targets.

This improves build time by about 70% when necessary targets have already
been built. Ensures every target is a no-op and prevents DroidDocs from
building.

Also adds -b and -t params to atest. This was taken from BIT. It allows
a user to specify the phase they want to run: BUILD, INSTALL, or TEST (BIT).
I haven't seperated out the INSTALL phase yet, but this seperates BUILD
and TEST phases. I like this a lot more than --skip-build since it matches
what they are already using and provides more functionality (like
the functionality needed to performance test atest).

Bug: b/69270230
Test: run_atest_unittests.sh
      atest -b CtsFileSystemTestCases:AlmostFullTest#testRandomRead
      atest -t CtsFileSystemTestCases:AlmostFullTest#testRandomRead
      atest CtsFileSystemTestCases:AlmostFullTest#testRandomRead

Trade Federation (TF / tradefed)

TF is a test harness used to drive Android automated testing. It runs on test hosts and monitors the connected devices, handling test scheduling & execution and device management.

Other test harnesses like Compatibility Test Suite (CTS) and Vendor Test Suite (VTS) use TF as a basis and extend it for their particular needs.

Building TF:

  • source build/envsetup.sh
  • tapas tradefed-all
  • make -j8
