target, record: add PTID argument to to_record_is_replaying

The to_record_is_replaying target method is used to query record targets if
they are replaying.  This is currently interpreted as "is any thread being
replayed".

Add a PTID argument and change the interpretation to "is any thread matching
PTID being replayed".

Change all users to pass minus_one_ptid to preserve the old meaning.

The record full target does not really support multi-threading and ignores
the PTID argument.

gdb/
	* record-btrace.c (record_btrace_is_replaying): Add ptid argument.
	Update users to pass minus_one_ptid.
	* record-full.c (record_full_is_replaying): Add ptid argument (ignored).
	* record.c (cmd_record_delete): Pass inferior_ptid to
	target_record_is_replaying.
	* target-delegates.c: Regenerated.
	* target.c (target_record_is_replaying): Add ptid argument.
	* target.h (struct target_ops) <to_record_is_replaying>: Add ptid
	argument.
	(target_record_is_replaying): Add ptid argument.
