gsk: Add GskGLDriver We can move the caching and management of textures, VAOs, and state of the GL machinery into a single object, GskGLDriver.

gsk: Add check on GL_MAX_TEXTURE_SIZE We should check (once) what's the maximum GL texture size and then use that size to check when we create any GL texture, to avoid errors.

gsktexture: Allow attaching render data to textures This allows renderers (or anyone really) to attach "render data" to textures. Only the first render data sticks. You can gsk_texture_set_render_data() with the key you will use to look the data up again, and if no data has been set yet, yours will be set. You can retrieve this data via gsk_texture_get_render_data() later on. If your data has been cleared, NULL will be returned. When gsk_texture_clear_render_data() is called (which the texture will call when it is finalized), your destory notify will be called and you have to release your render data. The GL driver uses this to attach texture ids to GskTextures.

Each VAO is marked as free at the end of the frame, and if it's not reused in the following frame, it gets dropped.
