test: Add on-device test for calculating MPU regions for RW
MPU logic needs to represent RW with no more than 2 MPU regions
when locking RW. Add on-device unit test for this calculation.
BRANCH=none
BUG=b:155410753
TEST=make -j BOARD=bloonchipper
TEST=make -j BOARD=nucleo-f412zg test-mpu
Then flash the test binary to nucleo board
runtest on device ==> Pass
