Add InstrProfilingPlatformFuchsia.c to profiler_builtins All other Platform files included in `llvm-project/compiler-rt` were present, except Fuchsia. Now that there is a functional end-to-end version of `-Zinstrument-coverage`, I need to start building and testing coverage-enabled Rust programs on Fuchsia, and this file is required. r? @tmandry FYI, @wesleywiser
