1. Make class TestSuite own more than one TestConfig and update clients accordingly.
2. There are some complication to avoid reloading same TestConfig twice when exec dir is in tree. Add a TestConfig cache key'd on its file path to solve the problem. (llvm\utils\lit\tests\Inputs\exec-discovery-in-tree)
