And add ifndef guards for cases were do have support for it.
While at it I need to change how we build it due to:
'meson.build:21:0: ERROR: Value "false" (of type "string") for combo
option "Enable support for vc4's KMS API." is not one of the choices.
Possible choices are (as string): "enabled", "disabled", "auto".'

NV15/20/30 are a family of 10bpc YUV formats which have 4
horizontally-adjacent samples packed into a 40-bit cluster. The
difference between 15/20/30 is in the subsampling.
No fallbacks are provided, as there is no format pairing which would
allow us to sensibly unpack the clusters.

These formats are useful because they are often easier to produce
on CPU than half-float formats, and abgr16161616 has both >= 10bpc
color channels and adequate alpha, unlike abgr2101010.
The 16-bpc textures created from buffers with these formats require
the GL_EXT_texture_norm16 extension.
As WL_SHM_FORMAT_ABGR16161616 was introduced in libwayland 1.20,
update Weston's build requirements and CI.
The formats also needed to be registered in the pixel format table,
and defined in a fallback path if recent libdrm is not available.

This header is for sharing fallback definitions for drm_fourcc.h. A new
test in tests/yuv-buffer-test.c is going to be needing XYUV8888 format,
and more new formats will be expected with HDR supports.
Share these fallback definitions in one place instead of copying them
all over.
All users of drm_fourcc.h are converted to include weston-drm-fourcc.h
instead for consistency: have the same definitions available everywhere.
