Clear JIT cache on exit (#1518)

* Initial cache memory allocator implementation

* Get rid of CallFlag

* Perform cache cleanup on exit

* Basic cache invalidation

* Thats not how conditionals works in C# it seems

* Set PTC version to PR number

* Address PR feedback

* Update InstEmitFlowHelper.cs

* Flag clear on address is no longer needed

* Do not include exit block in function size calculation

* Dispose jump table

* For future use

* InternalVersion = 1519 (force retest).
