meta: Convert _mesa_meta_bind_fbo_image to take a gl_framebuffer instead of a GL API handle

Also change the name of the function to
_mesa_meta_framebuffer_texture_image.  The function is basically a
wrapper around _mesa_framebuffer_texture (which is used to implement
glFramebufferTexture1D and friends), so it makes sense for it's name to
be similar to that.

The next patch will clean _mesa_meta_framebuffer_texture_image up
considerably.
