Eladash e4abd3dc5a SPU: Do not ignore pending PUT tranfers just becase GET may not be cache-line atomic 
This is not the proper way to emulate non-atomic GET tranfers, as it makes it seems as if PUT atomic tranfers arent atomic. (TODO)
Incomplete GET cache line accesses still do not verify data though.

Eladash 5d1fc546a8 SPU MFC: Fix MFC_WrTagUpdate channel count 
Always report available, in realhw this is just a hint if the previous tag update hasnt been checked yet by the MFC, avoiding blocking writes and allowing the SPU to execute some code while it processes the previous update request.
Except for MFC_TAG_UPDATE_IMMEDIATE, where it also waits for MFC to process it.

- Make SPU accurate GET transfers on non-TSX not modify reservation lock bits.
- Add some optimization regarding to unmodified data reservations writes.

sys_spu: Fix race in sys_spu_thread_group_destroy and other minor fixes (#8182) 
* sys_spu: Fix race in sys_spu_thread_group_destroy and other minor fixes

* SPU: Wait for all threads to have error codes if exited by sys_spu_thread_exit

On last thread in group to run.

* sys_spu: Fix sys_spu_thread_group_start

* fixup ad fix sys_spu_thread_group_terminate

idk why "- !group->running" was put in the first place but its probably no longer relevant due to other changes and was causing other issues such as not always waiting for last SPU thread to set group state to INITIALIZED.
