disp: msm: sde: expand dsc range_bpg_offset to support 10bpc

DSC driver is applying the range_bpg_offset values for 8 bpc/8bpp
to all compression ratios. This results in invalid DSC configuration
in 10bpc mode and sink is not able to decode this image resulting in
black screen.

This change adds a table of range_bpg_offset values to capture the
configuration for different bpc/bpp combinations.
