usb: typec: tcpm: Add support for Battery Cap response message
Add support for responding to Get_Battery_Cap (extended) request with a
a Battery_Capabilities (extended) msg. The requester will request
Battery Cap for a specific battery using an index in Get_Battery_Cap. In
case of failure to identify battery, TCPM shall reply with an
appropriate message indicating so.
As the Battery Cap Data Block size is 9 Bytes (lesser than
MaxExtendedMsgChunkLen of 26B), only a single chunk is required to
complete the AMS.
Support for Battery_Capabilities message is required for sinks that
contain battery as specified in USB PD Rev3.1 v1.8
("Applicability of Data Messages" section).
