drm/i915/dp: Track the detailed DSC slice configuration

Add tracking for the DP DSC pipes-per-line and slices-per-stream value
in the slice config state and compute the current slices-per-line
(slice_count) value using this slice config. The slices-per-line value
used atm will be removed by a follow-up change after converting all the
places using it to use the slice config instead.

For now the slices-per-stream value is calculated based on the
slices-per-line value (slice_count) calculated by the
drm_dp_dsc_sink_max_slice_count() / intel_dp_dsc_get_slice_count()
functions. In a follow-up change these functions will be converted to
calculate the slices-per-stream value directly, along with the detailed
slice configuration.
