Drop unnecessary check which allows enabling of lossless write through
compression (HiZ + CCS) for D16_UNORM format on Gen12+.
We had misleading HSD information previously which used to claim that
compression can not be supported for 16bpp format. Although BSpec does
not have any restriction for D16_UNORM format.

Those format have correct descriptions already with the exception of
the planar format. In that case we introduce an assert.
This fine because we don't use the planar format in any of our
drivers. There are restrictions on how the addresses of the 2 planes
are relative to one another which make this annoying. The sampler is
also more limited than what we can do with a shader snippet.

We also delete the badly named isl_surf_supports_hiz_ccs_wt. The name
is misleading because it doesn't return whether or not the surface
supports HiZ+CCS in write-through mode (any single-sampled HiZ+CCS
capable surface does) but rather a heuristic decision about whether or
not we want to enable write-through mode based on the usage flags in the
isl_surf.

Aligning phys_level0_sa by the compression block dimension prior to
mipmap layout causes the layout of compressed surfaces to differ from
the sampler's expectations in certain cases. The hardware docs agree:
From the BDW PRM, Vol. 5, Compressed Mipmap Layout,
The compressed mipmaps are stored in a similar fashion to
uncompressed mipmaps [...]
The following exceptions apply to the layout of compressed (vs.
uncompressed) mipmaps:
* [...]
* The dimensions of the mip maps are first determined by applying
the sizing algorithm presented in Non-Power-of-Two Mipmaps
above. Then, if necessary, they are padded out to compression
block boundaries.
The last bullet indicates that alignment should not be done for
calculating a miplevel's dimensions, but rather for determining miplevel
placement/padding. Comply with this text by removing the extra
alignment.
Fixes some fbo-generatemipmap-formats piglit failures on all tested
platforms (SNB-KBL).
