These aren't real formats. They cannot be used with
RenderbufferObjects, Textures, or anything else visible through the GL
API. The only purpose is to support YUYV textures imported through
EGL_image_external. There is hardware that can sample from this
subsampled format, but the hardware does not do the colorspace
conversion automatically.
v2: Treat these formats as compressed. This is a lie, but it seems to
be a less egregious lie than what I was doing before. It also passes
'ninja test'.

According to isl_gfx7.c:264, the display engine does not support Y
tiled buffers prior to Skylake. But we exposed I915_FORMAT_MOD_Y_TILED
even when querying for a list of modifiers with PIPE_BIND_SCANOUT set,
which we can't support. That led to crashes later when we tried to
create such an image, and isl rightly denied it.
Fixes crashes in wflinfo since c03e79d783, but the bug exists before
that and it's probably worth a stable backport even without that patch.

This duplicates a bit of code from ISL, but the isl_gfx6_filter_tiling
function that we ought to use to filter things relies on surf_info,
which we don't have at this stage. This is probably good enough.

We're supposed to map a floating-point value too large to be represented
as fp16 to infinity, however round-to-zero naturally rounds it down to
the largest representable fp16 number instead. The blob emits a bunch of
fixup code to work around this, but instead we can just do what all the
other drivers seem to do and use round-to-nearest-even instead.
