IDM: Implement lock-free smart pointers (#16403)
Replaces `std::shared_pointer` with `stx::atomic_ptr` and `stx::shared_ptr`.

Notes to programmers:

* This pr kills the use of `dynamic_cast`, `std::dynamic_pointer_cast` and `std::weak_ptr` on IDM objects, possible replacement is to save the object ID on the base object, then use idm::check/get_unlocked to the destination type via the saved ID which may be null. Null pointer check is how you can tell type mismatch (as dynamic cast) or object destruction (as weak_ptr locking).
* Double-inheritance on IDM objects should be used with care, `stx::shared_ptr` does not support constant-evaluated pointer offsetting to parent/child type.
* `idm::check/get_unlocked` can now be used anywhere.

Misc fixes:
* Fixes some segfaults with RPCN with interaction with IDM.
* Fix deadlocks in access violation handler due locking recursion.
* Fixes race condition in process exit-spawn on memory containers read.
* Fix bug that theoretically can prevent RPCS3 from booting - fix `id_manager::typeinfo` comparison to compare members instead of `memcmp` which can fail spuriously on padding bytes.
* Ensure all IDM inherited types of base, either has `id_base` or `id_type` defined locally, this allows to make getters such as `idm::get_unlocked<lv2_socket, lv2_socket_raw>()` which were broken before. (requires save-states invalidation)
* Removes broken operator[] overload of `stx::shared_ptr` and `stx::single_ptr` for non-array types.

Eladash 64997662d2 LV2: Fixup for IPC
* Fix typo in lv2_obj::create.
* Always save ipc_key as 0 for non-shared object creations, regardless of thbe value set by creation attribute.
* Show IPC key of shared memory (sys_mmapper) memory objects in kernel explorer.

LV2: Improve IPC support (#10206)
* Remove custom event queue's IPC management of favour of universal LV2 approach.
* Move ipc_manager to FXO.
* Fix ipc_manager internal storage memory leak: deallocate entry when IPC object destroyed.
* Rewrite lv2_obj::create to be simpler (remove many duplicated code).
* Always execute lv2_obj::create under both IPC and IDM mutexes at once (not in non-atomic single-steps). Fixing potential case where concurrency can cause IDM to contain 2 or more different objects with the same IPC key with SYS_SYNC_NOT_CARE (instead of the same object).
* Do not rely on smart ptr reference count to tell if the object exists. Use similar approach as event queues as it makes error checkings accurate.
* Optimize lv2_event_port by using std::shared_ptr for queue which wasn't allowed before.

Lassi Hämäläinen e9e87b8bd9 Add missing #includes to header files
- Multiple header files where missing #includes to other headers that
  where used in the header. Correct header was included in correct
  order in source files which caused everything to compile.
- Added missing #includes so header files correctly include all their
  dependencies and fixes problems with IDEs being unable to parse
  headers correctly due to missing symbols

Lassi Hämäläinen 499035512b Split Emu/Memory into more logical headers
- Add vm_locking.h and vm_reservation.h and move relevant functions
  and types to these headers.
- Change include order and make vm_ptr.h, vm_var.h and vm_ref.h headers
  usable invidually and them including vm.h instead of other way around
- Because usage of vm::ptr now requires including vm_ptr.h instead of
  vm.h updated multiple #includes
- Added additional #includes to vm_reservation.h and vm_locking to
  where vm::reservation_* and locking related functions are used

eladash 4a28319edf Implement SPU page faults notifications
* Implement both RawSPU and threaded SPU page fault recovery
* Guard page_fault_notification_entries access with a mutex
* Add missing lock in sys_ppu_thread_recover_page_fault/get_page_fault_context
* Fix EINVAL check in sys_ppu_thread_recover_page_fault, previously when the event was not found begin() was erased and
CELL_OK was returned.
* Fixed page fault recovery waiting logic:
- Do not rely on a single thread_ctrl notification (unsafe)
- Avoided a race where ::awake(ppu) can be called before ::sleep(ppu) therefore nop-ing out the notification
* Avoid inconsistencies with vm flags on page fault cause detection
* Fix sys_mmapper_enable_page_fault_notification EBUSY check
from RE it's allowed to register the same queue twice (on a different area) but not to enable page fault notifications twice
