TCPM: Separate Discovery into its own module
Discovery can be a separate feature from DFP mode entry, as any data
role can run discovery in PD 3.0. Additionally, boards may want to
enable discovery separate from full EC mode entry so put this feature
behind a new CONFIG indicating its scope.
BRANCH=None
BUG=b:266714542
LOW_COVERAGE_REASON=only moving functions to a new file, b/267964449
filed to track expanding the testing of these functions later
TEST=./twister -T ./zephyr/test, run on both nipperkin (ECOS) and skyrim
(zephyr) to confirm cable and device identities are being reported
correctly
