Feature/iop emulator (#244)

* refactor: from guest  threads to EE scheduler

* feat: bad wip mpeg fix for code veronica

* feat: cheap copy from host
feat: small perf o vsync tick

* feat: added EE clock Hz
fix: fix MPEG out of sync with new EE refactor

* fix: fix lotr tests

* fix: fix cri dtx loading
fix: fix wrong mmi instruction translation
fix: fix thread info params
feat: added EE  timers decoder and consumer
feat: split SFI and IOP memory to prevent collision and overrides

* feat: revert wrong changes

* refactor: change GS architecture

* feat: IOP emulator
refactor: codegen to catch callbacks on mips code
feat: added a lot of entries or IOP emulator

* feat: analyzer resolve the complete constant-producing sequence with five-instruction backward scan stopped at LUI and therefore

* feat: remove recompiled version of GetRomName
refactor: split IOP emulator logic
feat: added more HLE IOP modules
feat: added ps2_path

* eat: enhance ELF parser with improved callable entry detection and control flow analysis

* feat: update memory hint handling and enhance entry point discovery logic

* feat: add SET_GPR_ZE32 macro for zero-extending loads with unsigned semantics

* refactor: Refactor PS2 IOP Host Adapter and Memory Management
feat: Added PS2Vfs for virtual file system operations, including file opening, reading, writing, and path resolution.
feat: Improve VIF1 data processing to handle GIF image packets more efficiently.

* feat: added a lot of tests

* fix: fix texture caching
feat: wip multi version on dbcman

* feat: remove LLE IOPs
