The current default is r32g32b32a32 but it requires special support
which is not available on all GPUs, so it is not a very convenient
default.
Instead of changing the default making it different from RTV resoures,
the format is required to always be explicit for UAVs.
The exceptions are counter_buffer and buffers with "stride", which don't
require a format because it is already implied.
In the case two uav descriptors are mapped to the same variable, and one is
read from while the other is not, the variable would get the NonReadable
decorator, while being read from later.
The existing code reuses the same SPIR-V variable for all descriptors mapped to
the same Vulkan binding, and applies the NonReadable decoration based on the
VKD3D_SHADER_DESCRIPTOR_INFO_FLAG_UAV_READ only. This potentially causes the
decoration to be applied twice, should two non-read descriptors be mapped to
the same variable, which isn't allowed in SPIR-V, and the validator complains.
CTAB type correctly reflects matrix majority, unlike effects
type data that does not respond to majority modifiers at all.
It doesn't transpose default values either.

This fixes a lot of internal compiler errors with assignment operators,
especially bitwise ones. The bitwise-assignment test has the motivating
examples.
The existing code sets "stageFlags" to VK_SHADER_STAGE_ALL when
"use_vk_heaps" is true, but doesn't adjust the visibility. This
potentially violates the "Any two elements of pPushConstantRanges must
not include the same stage in stageFlags" constraint, and causes the
validation layers to complain accordingly.
