160b131de3 types.hpp: implement smin, smax, amin, amax 
Rewritten the following global utility constants:
`umax` returns max number, restricted to unsigned.
`smax` returns max signed number, restricted to integrals.
`smin` returns min signed number, restricted to signed.
`amin` returns smin or zero, less restricted.
`amax` returns smax or umax, less restricted.

Fix operators == and <=> for synthesized rel-ops.

Atomic waiting refactoring (#9208) 
* Use atomic waitables instead instead of global thread wait as often as possible.
* Add ::is_stopped() and and ::is_paued() which can be used in atomic loops and with atomic wait. (constexpr cpu flags test functions)
* Fix notification bug of sys_spu_thread_group_exit/terminate. (old bug, enhanced by #9117)
* Function time statistics at Emu.Stop() restored. (instead of current "X syscall failed with 0x00000000 : 0")

e40b76b253 sys_lwcond: Extract protocol from lwmutex at creation 
This is the only reason theres a need to specify lwmutex_sq id at creation. unlike sys_cond, lwcond isn't connected to lwmutex at the lv2 level.
SYS_SYNC_RETRY fix is done explicitly at the firmware level.
This fixes issues when the original lwcond and lwmutexol data got corrupted or deallocated, this can happen when the program simply memcpy the control data to somewhere else.
Or if it uses direct lv2 the lwcond conrol param can even be NULL which will make it access violate when dereferncing it. (This param is unchecked and can be anything)
