[GTK] Crash in GraphicsContextGLGBM::allocateDrawBufferObject
https://bugs.webkit.org/show_bug.cgi?id=255398
Reviewed by Michael Catanzaro.
GBMBufferSwapchain::getBuffer() can return nullptr for several reasons,
so we need to handle that case in
GraphicsContextGLGBM::allocateDrawBufferObject(). This also adds error
messages for the cases where getBuffer() returns nullptr, and returns
earlier without creating any buffer when the given format is
unsupported.
