Revert^2 "Remove test_per_src from ART tests."

Second attempt at this, which fixes the asan failures.

Remove test_per_src since it is not supported by atest.
Replace it with gtest_isolate which is transparent to atest,
and which still allows us to run tests in parallel.

The size of test binaries halves (from 1GB to 0.5GB).
Test run-time on host is unchanged.
Test run-time on target is 4x faster (tested on walleye).

Added a gtest_main.cc with the gtest isolated main function,
and ART-specific initialization.

Bug: 147819342

Test: m test-art-host-gtest
Test: art/tools/run-gtests.sh
Test: art/test/testrunner/run_build_test_target.py art-gtest-asan
