  [WPE] Add support for using skia compositor with the legacy API
https://bugs.webkit.org/show_bug.cgi?id=314941

Reviewed by Nikolas Zimmermann.

For the legacy API we need to create the GrContext for the compositor GL
context that uses a native surface. So this patch adds
PlatformDisplay::setSkiaGLContextForCurrentThread() to able to set the
thread GrContext instead of being automatically created with an
offscreen context. Then we need to create a SkSurface wrapping the
default frame buffer of the gl context in
AcceleratedSurface::RenderTargetWPEBackend.
