- while resuming threads - after checking threads stopped immediately
check for FE bit, if set do not generate thread stop event
- if PageFault occured, report stop event based on pagefault event

When a thread is stopped due to potential page fault
we must check AIP against start IP to ensure it is not
a newly started thread accidentally caught by PF algorithm

- do not allocate state save area every time attention event
is handled
- keep allocated memory for subsequent events
- remove not needed DBEUG_BREAK

- check threads with attention state before reading SR_IDENT
- memory read is costly, for threads already in stopped state
there is no need to read sr_ident and check thread state again
- single stepping one thread performance is substantially improved,
by the factor of 6x

System Routine changes for implementing large-grf debugging
will result in GRF count of 256 being reported for kernels
in all GRF modes. Applications using L0 Debug API do not
yet have a way to determine actual GRF count for kernel.
This commit is a temporary adjustment to avoid breaking debug
API users after new system routine is enabled.
This problem will be fully solved in follow up patch with switch to
zetDebugGetThreadRegisterSetProperties

Current SIP implementation has constant reg descs for all threads.
Initial implementation of this API always returns same reg descs as the
non-thread version of API. When SIP exposes per-thread reg descs,
this API will be updated to expose them.

- when resume(all) is called - all threads' sr counter needs to be
verified. Reading state save area separately for all threads takes
longer than reading whole state save area once. State save area is
only read again if sr counter wasn't updated
- fail while reading state save area means threads might have completed
execution
- this fix optimizes time spent in resume(all), that may be called before
debugger detaches

- reading state save area for every threads takes too long when all
application threads have completed and there are stale ATT events to
process
- on detach gdb seemed to be frozen waiting for ATT event to be handled
- fix is to read state save area once - and check SIP counter for every
thread in ATT bitmask
