scsi: libsas: Add sas_execute_internal_abort_single()
The internal abort feature is common to hisi_sas and pm8001 HBAs, and the
driver support is similar also, so add a common handler.
Two modes of operation will be supported:
- single: Abort a single tagged command
- device: Abort all commands associated with a specific domain device
A new protocol is added, SAS_PROTOCOL_INTERNAL_ABORT, so the common queue
command API may be re-used.
Only add "single" support as a first step.
