Support capstone output for the '-F +brstackinsn' branch dump.
The new output is enabled with the new field 'brstackdisasm'.
This was possible before with --xed, but now also allow it for users
that don't have xed using the builtin capstone support.
Before:
perf record -b emacs -Q --batch '()'
perf script -F +brstackinsn
...
