I didn't test "nvk: Fix maxVariableDescriptorCount with iub" as
thoroughly as I should have and it regressed
dEQP-VK.api.maintenance3_check.descriptor_set because we were then
violating the requirement that maxPerSetDescriptors describes a limit
that's guaranteed to be supported (and reported as supported in
GetDescriptorSetLayoutSupport).
That commit was also based on a misreading of nvk_nir_lower_descriptors.c
where I thought that the end offset of an inline uniform block needed to
be less than the size of a UBO. That is not the case - on closer
inspection that code gracefully falls back to placing IUBs in globablmem
if necessary. So, we can afford to be less strict about our IUB sizing
and only require that IUBs follow the existing limit imposed by
maxInlineUniformBlockSize.
