hwc2: Add support for multiple displays
- Add support for an additional display which can be either a builtin
display or pluggable display.
- Restructure HWCDisplayPrimary as HWCBuiltIn and HWCDisplayExternal
as HWCDisplayPluggable.
- Refactor hotplug handling. Iterate through all pluggable displays,
and check present connection status. Connect/disconnect a given
display if connection status has changed.
