On MTL, gt->scratch was using stolen lmem. An MI_SRM to stolen lmem
caused a hang that was attributed to saving and restoring the GPR
registers used for noa_wait.
Add an additional page in noa_wait BO to save/restore GPR registers for
the noa_wait logic.

On MTL, gt->scratch was using stolen lmem. An MI_SRM to stolen lmem
caused a hang that was attributed to saving and restoring the GPR
registers used for noa_wait.
Add an additional page in noa_wait BO to save/restore GPR registers for
the noa_wait logic.
