TCPMv2: PE: Add mechanism to request source power role
This CL makes the function pd_can_source_from_device()
overridable. This default implementation is used in deciding whether
to request a power role swap. By making this overridable, boards have
the option of implementing custom per port policy for requesting power
role swaps.
BUG=b:182441965
BRANCH=None
TEST=verfied that on quiche when attaching as a sink that a power role
swap request is generated. Previously, quiche relied on the host
requesting a power role swap.
