Vulkan: Fix some issues with CacheByRange (#3743)
* Fix some issues with CacheByRange - Cache now clears under more circumstances, the most important being the fast path write. - Cache supports partial clear which should help when more buffers join. - Fixed an issue with I8->I16 conversion where it wouldn't register the buffer for use on dispose. Should hopefully fix issues with https://github.com/Ryujinx/Ryujinx-Games-List/issues/4010 and maybe others. * Fix collection modified exception * Fix accidental use of parameterless constructor * Replay DynamicState when restoring from helper shader
