    [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.
