Update FEATURE_VULKAN_HARDWARE_COMPUTE documentation

Browse Source 
Now that VK_KHR_variable_pointers is public, the documentation can be more
precise about the definition of FEATURE_VULKAN_HARDWARE_COMPUTE level 0.
Also document the maxPerStageDescriptorStorageBuffers requirement.

Bug: 34745152
Test: make docs
