Persistent process is ProcessRecord.isPersistent().

Browse Source 
Persistent process does not propagate BG-FGS-start capability
down to service over binding, the "persistent process" here is
ProcessRecord.isPersistent() (manifest file has android:persistent="true")
instead of the process's procstate is PROCESS_STATE_PERSISTENT, because app
could also get procstate PROCESS_STATE_PERSISTENT when it is bound by system_server.

Bug: 226461824
