Add a test target with sharding support to the CMake build.
Two major things going on here:
- One target is created for each file in test-data.sha1 (testdata_N),
and the testdata target now depends on all testdata_N targets. The
testdata build rule can now run with as many jobs as there are
input files to speed up test data download.
- GTest sharding support has been added to the tests via a runtests
custom build target. First, the number of processors is detected,
and then a custom target is created for each processor (test_N).
Once each test_N target is created, the runtests custom target
is created, and then made to depend on each test_N target. When
CMake is unable to detect the number of processors 10 test targets
are created. Each custom target then sets the GTEST_SHARD_INDEX and
GTEST_TOTAL_SHARDS environment variables, allowing GTest to handle
sharding internally.
