Summary: Also add the corresponding XFAILs to tests that require filesystem. The approach taken to mark <filesystem> as unavailable in this patch is to mark all the header as unavailable using #pragma clang attribute. Marking each declaration using the attribute is more intrusive and does not provide a lot of value right now because pretty much everything in <filesystem> requires dylib support, often transitively. This is an alternative to https://reviews.llvm.org/D59093. A similar (but partial) patch was already applied in r356558.
