thread: Put all important SDL_CreateThread internal data into SDL_Thread.

This avoids the need to malloc something extra, use a semaphore, etc, and
fixes Emscripten with pthreads support, which might not spin up a web worker
until after SDL_CreateThread returns and thus can't wait on a semaphore at
this point in any case.

Fixes Bugzilla #5064.
