framebuffer: Add a getter for the framebuffer format

This adds a new function, cogl_framebuffer_get_color_format() to be able
to query the common pixel format for any color buffers attached to a
given CoglFramebuffer. For example an offscreen framebuffer created
using cogl_offscreen_new_to_texture() would have a format matching the
texture.
