Subject: Add a simple Pools Limiter. (#1830)

* Added support for offline invalidation, via PPTC, of low cq translations replaced by high cq translations; both on a single run and between runs.

Added invalidation of .cache files in the event of reuse on a different user operating system.

Added .info and .cache files invalidation in case of a failed stream decompression.

Nits.

* InternalVersion = 1712;

* Nits.

* Address comment.

* Get rid of BinaryFormatter.

Nits.

* Move Ptc.LoadTranslations().

Nits.

* Nits.

* Fixed corner cases (in case backup copies have to be used). Added save logs.

* Not core fixes.

* Complement to the previous commit. Added load logs. Removed BinaryFormatter leftovers.

* Add LoadTranslations log.

* Nits.

* Removed the search and management of LowCq overlapping functions.

* Final increment of .info and .cache flags.

* Nit.

* Free up memory allocated by Pools during any PPTC translations at boot time.

* Nit due to rebase.

* Add a simple Pools Limiter.

* Nits.

* Fix missing JumpTable.RegisterFunction() due to rebase.

Clear MemoryStreams as soon as possible, when they are no longer needed.

* Code cleaning.

* Nit for retrigger Checks.

* Update Ptc.cs

* Contextual refactoring of Translator. Ignore resetting of pools for DirectCallStubs.

* Nit for retrigger Checks.
