Implement host tracked memory manager mode (#6356)

Browse source 
* Add host tracked memory manager mode

* Skipping flush is no longer needed

* Formatting + revert unrelated change

* LightningJit: Ensure that dest register is saved for load ops that do partial updates

* avoid allocations when doing address space lookup

Add missing improvement

* IsRmwMemory -> IsPartialRegisterUpdateMemory

* Ensure we iterate all private allocations in range

* PR feedback and potential fixes

* Simplified bridges a lot

* Skip calling SignalMappingChanged if Guest is true

* Late map bridge too

* Force address masking for prefetch instructions

* Reprotection for bridges

* Move partition list validation to separate debug method

* Move host tracked related classes to HostTracked folder

* New HostTracked namespace

* Move host tracked modes to the end of enum to avoid PPTC invalidation
