ANDROID: usb: typec: tcpci: Add vendor hook to mask vbus present

This hook is for addressing hardware anomalies where
TCPC_POWER_STATUS_VBUS_PRES bit can return 0 even before falling
below sSinkDisconnect threshold.

Handler has to set bypass to override the value that would otherwise
be returned by this function.
Handler can set vbus or clear vbus to indicate vbus present or absent
