We were not making any distinction between e.g. the "Apple-flavored" libc++ built from trunk and the system-provided standard library on Apple platforms. For example, any test that would be XFAILed on a back-deployment target would unexpectedly pass when run on that deployment target against the tip of trunk Apple-flavored libc++. In reality, that test would be expected to pass because we're running against the latest libc++, even if it is Apple-flavored. To solve this issue, we introduce a new feature that describes whether the Standard Library in use is the one provided by the system by default, and that notion is different from the underlying standard library flavor. We also refactor the existing Lit features to make a distinction between availability markup and the library we're running against at runtime, which otherwise limit the flexibility of what we can express in the test suite. Finally, we refactor some of the back-deployment versions that were incorrect (such as thinking that LLVM 10 was introduced in macOS 11, when in reality macOS 11 was synced with LLVM 11). Fixes #82107
