  [GTK][WPE] Use GBM when available for WebGL in the web process
https://bugs.webkit.org/show_bug.cgi?id=279122

Reviewed by Alejandro G. Castro.

The solution we found to get the internal texture created by ANGLE is
weak, so we should only use it as fallback for systems where DMA-BUF is
not available. This patch adds a new impementation using the new
CoordinatedPlatformLayerBuffer to add a new one for DMABuf buffers. It
also adds a new class GraphicsContextGLTextureMapperGBM that will be
used also for the GPU process implementation.
