drm/i915/display: add intel_display_limits.h for key enums



Move a handful of key enums to a new file intel_display_limits.h. These
are the enum types, and the MAX/NUM enumerations within them, that are
used in other headers. Otherwise, there's no common theme between them.

Replace intel_display.h include with intel_display_limit.h where
relevant, and add the intel_display.h include directly in the .c files
where needed.

Since intel_display.h is used almost everywhere in display/, include it
from intel_display_types.h to avoid massive changes across the
board. There are very few files that would need intel_display_types.h
but not intel_display.h so this is neglible, and further cleanup between
these headers can be left for the future.

Overall this change drops the direct and indirect dependencies on
intel_display.h from about 300 to about 100 compilation units, because
we can drop the include from i915_drv.h.
