drm/amd/display: Remove RMCM tetrahedral cube from dc_plane_state

Browse source

[Why&How]
MCM and RMCM both took their cube from struct tetrahedral_params, which is
embedded by value in dc_3dlut and therefore in dc_plane_state and dc.scratch.
RMCM needs a 33x33x33 cube, but that cube is ~421KB, so enabling it in the
shared union - where tetrahedral_33 was left commented out - would push
sizeof(struct dc) past the kmalloc MAX_PAGE_ORDER limit and break kunit
and other allocations.
Drop the unused struct tetrahedral_33x33x33 definition and lut_dim.
