* Timing: Optimize Timestamp Aquisition
Currently, we make use of Environment.TickCount in a number of places. This has some downsides, mainly being that the TickCount is a signed 32-bit integer, and has an effective limit of ~25 days before overflowing and wrapping around. Due to the signed-ness of the value, this also caused issues with negative numbers. This resolves these issues by using a 64-bit tick count obtained from Performance Counters (via the Stopwatch class). This has a beneficial side effect of being significantly more accurate than the TickCount.
* Timing: Rename ElapsedTicks to ElapsedMilliseconds and expose TicksPerX
* Timing: Some style changes
* Timing: Align static variable initialization
* (Re)Implement format reinterpretation, other changes
* Implement writeback to guest memory, some refactoring
* More refactoring, implement reinterpretation the old way again
* Clean up
* Some fixes on M2MF (old Dma engine), added partial support for P2MF, fix conditional ssy, add Z24S8 zeta format, other fixes
* nit: Formatting
* Address PR feedback
* Initial implementation of the texture cache
* Cache vertex and index data aswell, some cleanup
* Improve handling of the cache by storing cached ranges on a list for each page
* Delete old data from the caches automatically, ensure that the cache is cleaned when the mapping/size changes, and some general cleanup
