fpsensor: Add API to check FP sensor encryption status.
Add EC command for the host to query FP sensor encryption status.
Currently it's just FP TPM seed has been set or not.
Add unit test for this command. Also add ectool command for querying
encryption status.
BRANCH=nocturne
BUG=chromium:952275
TEST=ran unittests
TEST=tested enrollment, matching and multifinger on DUT nocturne.
TEST=tested querying sensor encryption status using ectool.
