  [Win] WTF::RunLoop: RegisterClass has to be called in the main thread before creating other threads
https://bugs.webkit.org/show_bug.cgi?id=255624

Reviewed by Don Olmstead.

CreateWindow was randomly failing in the GPU process for WebGL tests
for Windows port. This seems to be a theading issue of calling
CreateWindow in a different thread rather than one called
RegisterClass. RegisterClass has to be called in the main thread
before creating other threads. Reverted 228617 at main.
