test: body_detection: add unittest for algorithm
Add test to check if the algorithm of body detection is correct.
There are three testcases:
OnBody: always in on-body state, should not change to off-body
Off to On: change state from off-body to on-body
On to Off: change state from on-body to off-body
BRANCH=None
