Log Message:

[Win] Crash in GLContext::makeContextCurrent under
WCSceneContext::makeContextCurrent
https://bugs.webkit.org/show_bug.cgi?id=264550
Reviewed by Don Olmstead.
Running layout tests was randomly observing assertion failures in GPU
process due to OpenGL context creation failures for Windows port. It
was relatively reproducible with the following invocation:
> python .\Tools\Scripts\run-webkit-tests --debug --iter=100 -f --no-retry
> --no-show compositing/shared-backing/backing-sharing-compositing-change.html
> compositing/shared-backing/move-sharing-child.html
In that cases, the HWND was already closed in UI process. We have to
check the GLContext validity and the return value of
makeContextCurrent in GPU process.
