Fix various issues caused by Vertex/Index buffer conversions (#3762)
* Fix various issues caused by #3679

- The arguments for the 0th dummy vertex buffer were incorrect - it was given an offset of 16 rather than a size of 16.
- The wrong size was used when doing `autoBuffer.Get` on a converted vertex buffer.
- The possibility of a vertex buffer being disposed and then rebound can rebindings to find a different buffer where the current range is out of bounds. Avoid binding when out of range to prevent validation errors.
- The above also affects generation of converted buffers, which was a bit more fatal. Conversion functions now attempt to bound input offset/size.

* Fix offset for converted buffer

Restride vertex buffer when stride causes attributes to misalign in Vulkan. (#3679)
* Vertex Buffer Alignment part 1

* Update CacheByRange

* Add Stride Change compute shader, fix storage buffers in helpers

* An AMD exclusive

* Reword

* Change rules - stride conversion when attrs misalign

* Fix stupid mistake

* Fix background pipeline compile

* Improve a few things.

* Fix some feedback

* Address Feedback

(the shader binary didn't change when i changed the source to use the subgroup size)

* Fix bug where rewritten buffer would be disposed instantly.
