Move common attention handling code from prelim in common linux
debug_session(.h/.cpp) files.
This common code could be shared to handle attention events for
prelim and xe driver based Eu Debug

- 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

- 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

- when no threads are executing, interrupt all may fail and debug break
fires - although error is handled and correct event is returned. To
prevent abort, debug break has to be removed

- before marking interrupt request check exception reason. If there is
exception other than forced exception or forced external halt treat
thread as stopped and generate distinct event for it.

- check threads with ATT only when more than one thread is resumed
- if single thread is resumed - check only that thread
- delay thread state check - allowing thread to reenter SIP

Single-stepping threads is based on resume() and THREAD_STOPPED events
To speed up single-stepping, stopped threads must be discovered
immediately after resume() is called.
This change is adding ATT scan and event generation in resume()
