simpleperf: add --size-limit option in record cmd.
--size-limit option stops recording when the recorded data
reaches the size limit. It is used by
run_simpleperf_without_usb_connection.py to avoid taking too much disk
space.
Bug: http://b/74198167
Test: run simpleperf_unit_test.
Test: run test.py.
