Implement support for multi-range buffers using Vulkan sparse mappings (#5427)

Browse source 
* Pass MultiRange to BufferManager

* Implement support for multi-range buffers using Vulkan sparse mappings

* Use multi-range for remaining buffers, delete old methods

* Assume that more buffers are contiguous

* Dispose multi-range buffers after they are removed from the list

* Properly init BufferBounds for constant and storage buffers

* Do not try reading zero bytes data from an unmapped address on the shader cache + PR feedback

* Fix misaligned sparse buffer offsets

* Null check can be simplified

* PR feedback
