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