This prepares the trap handler to support being used from simulators. Modifications to the arm64 simulator will be done in a follow-up CL. For now, the trap handler will be registered but not used in Wasm (we emit explicit bounds checks instead, as before). The implementation uses inline assembly, so it is only available on x64 POSIX systems for now. This is the main platform we use for testing and for fuzzing, so it should give us the test coverage we need. If needed, inline assembly for other platforms can be added later. The new code will be executed by the existing arm64 simulator bots, e.g. "V8 Linux - arm64 - sim".
