Revert 201202 "base: Support setting thread priorities generically."

Broke "sizes" by adding may static initializers.

> base: Support setting thread priorities generically.
> 
> This patch supports setting priorities across platforms
> at the PlatformThread level, by stashing thread id into the
> thread handle on linux/android.
> 
> Since this adds more platform specific code, and #ifdefs
> were starting to get unwieldy, all platform specific code
> is moved into _platform.cc files, with the exception of the
> 'default' implementation, which stay in _posix.
> 
> BUG=170549
