drm/i915/xe3p_lpd: Add FBC support for FP16 formats

Add supported FP16 formats for FBC. FBC can be enabled with
FP16 formats only when plane pixel normalizer block is enabled.
The follow up patches will handle the pixel normalizer block
configuration.

v2: changes related to comments to use better tracking of pixel
    normalizer
