This CL introduces the Fuchsia versions of the existing platform specific functions. For Fuchsia, we need to track the VMAR (https://fuchsia.dev/fuchsia-src/reference/kernel_objects/vm_address_region) of the Guarded Pool mapping, and for this purpose I added some platform specific data structure that remains empty on POSIX platforms. `getThreadID` is not super useful for Fuchsia so it's just left as a stub for now. While testing the changes in my Fuchsia tree, I realized that `guarded_pool_allocator_tls.h` should have closed the namespace before including `GWP_ASAN_PLATFORM_TLS_HEADER`, otherwise drama ensues. This was tested in g3, upstream LLVM, and Fuchsia (with local changes). Differential Revision: https://reviews.llvm.org/D90483
