lib/igt_debugfs: Add igt_pipe_crc_get_single and igt_pipe_crc_drain, v4.
Collecting CRC may result in a modeset and extra vblank waits. On some
tests this will increase the runtime a lot, so it makes sense to
keep it enabled, and only collect the most recent CRC when needed.
Changes since v1:
- Fix read_crc semantics. (Ville)
Changes since v2:
- Remove EAGAIN assert, can be reached from drain_crc.
Changes since v3:
- Do not infinitely loop in igt_pipe_crc_drain().
