Tadeu Zagallo 0f92639a96 Prevent RCTProfileTrampoline from getting stripped
Summary: public

I was using `dlsym` as a more elegant way of checking if the function was defined
to prevent crashes if running on an unsupported architecture, but Xcode might
strip the symbol, even with `.no_dead_strip`, if there's no references to the
compilation unit at all.

Replace it with an ugly `#if` that checks if it's any of the supported targets
and extern the function prototype.
