Thread safety analysis: Run more tests with capability attributes [NFC] Summary: We run the tests for -Wthread-safety-{negative,verbose} with the new attributes as well as the old ones. Also put the macros in a header so that we don't have to copy them all around. The warn-thread-safety-parsing.cpp test checks for warnings depending on the actual attribute name, so it can't undergo the same treatment. Together with D49275 this should fix PR33754.

Thread safety analysis: Test and document release_generic_capability The old locking attributes had a generic release, but as it turns out the capability-based attributes have it as well. Reviewed By: aaron.ballman Differential Revision: https://reviews.llvm.org/D87064
