fpsensor: Add timing statistics.
This commit adds some basic timing statistics around fingerprint
capture, matching, and overall timing for returning a response for a
fingerprint. A new host command is added, EC_CMD_FP_STATS, which
returns these metrics. Additionally, ectool has been extended with the
`fpstats` to command retrieve these metrics.
BUG=b:111316382
BRANCH=None
TEST=Flash nocturne_fp, perform capture and match, view results using
ectool and verify that they are reasonable.
