drm/i915/dp: Refactor intel_dp_in_hdr_mode() for broader reuse

Browse Source 
The intel_dp_in_hdr_mode() helper was previously defined in
intel_dp_aux_backlight.c but is generally useful beyond that
context. Move the function to intel_dp.c and declare it in
intel_dp.h to make it accessible to other DP-related code
paths that need to check HDR metadata state.

This is a pure refactor with no functional change and
prepares for a follow-up patch that uses this helper.
