perf: arm_spe: Suppress redundant ITRACE start records
PERF_RECORD_ITRACE_START establishes the initial thread context at the
beginning of a trace. Afterwards, decoders track the thread context using
context packets or recorded sched_switch events.
Call perf_event_itrace_started() when event starts to prevent perf core
from emitting redundant PERF_RECORD_ITRACE_START records on later
schedule-ins.
