display: Clean up binder interface

The current binder implementation is inflexible when it comes to
adding new input/output parameters. It also needs a lot of
boilerplate code written when adding a simple enable/disable type
command.

Instead, let clients specify the parcels they want to pass and
unparcel them at the end points only.
Please note that it is assumed that all commands coming in
need the same permission checks. If this is no longer the case,
some commands need to be split out on the receiver end in
IQService.cpp.
This change also simplifies the code end clients need to write.
They should be able to include QServiceUtils and call a single
function to set the binder up and make the call.

qdutils: Add display config to qdutils

This API is meant for system level users that need to get/set
various display attributes that are normally not available via
the regular Android framework channels.
Initially the APIs exposed are to check HDMI status, get display
attributes and set HSIC data.
Only physically connected displays are supported for now.

hwc: Add binder interface to get the visibleRegion

- This binder interface can be used by clients to know the
  active visible region for a display(pri/ext/virt)
- When external orientation is used, return the destFrame of
  the FrameBuffer layer, as its the viewFrame
