rhi: Include resource count in srb layout compatibility checks
Relevant for Vulkan, given that descriptorCount is part of
VkDescriptorSetLayoutBinding, meaning two srbs with arrays of
SampledTextures should only be reported as compatible if the
array size matches.
Also reduces the prealloc size for the VLAs. For Qt Quick even a
lower number would be sufficient, but we still keep the number
something fairly high in order to play nice with Quick3D.
Pick-to: 6.2
