This replaces the old macros LIBC_COPT_TEST_USE_FUCHSIA and LIBC_COPT_TEST_USE_PIGWEED with LIBC_COPT_TEST_ZXTEST and LIBC_COPT_TEST_GTEST, respectively. These are really not about whether the code is in the Fuchsia build or in the Pigweed build, but just about what test framework is being used. The gtest framework can be used in many contexts, and the zxtest framework is not always what's used in the Fuchsia build. The test/UnitTest/Test.h wrapper header now provides the macro LIBC_TEST_HAS_MATCHERS() for use in `#if` conditionals on use of gmock-style matchers, replacing `#if` conditionals that test the framework selection macros directly.
