lib/igt_fb: Add a helper to retreive the plane bpp for a given format
The format bpp for a given plane is stored in the static format_desc
structure and is not accessible to tests, which is inconvenient to
get the minimum stride for a format when testing various strides.
Add a simple helper to expose the information.
