usb_pe_drp: new unit test with mocks

Add a new unit test for usb_pe_drp with mocks for the various
subsystems that it will use.
The fake_prl module is already essentially a mock for the PRL layer,
so just move it into the mocks directory and make it available as
mock to other tests.

BUG=b:163421994
BRANCH=None
TEST=`make runhosttests` succeeds
