BB Retimer: Add CONFIG_USBC_RETIMER_INTEL_BB_VPRO_CAPABLE
Add config to enable host support for vPro. S0ix issue is observed on
connecting vPro dock to host without vPro capability. BB Retimer
handling for vPro dock needs to be enabled only for vPro capable host.
BRANCH=None
BUG=b:220805370
TEST=Verify S0ix transition is working without any wakes on redrix and
voxel when vpro dock is connected.
