Add support for Boot Control Hal 1.1.

The 1.1 impl lib is named as "android.hardware.boot@1.0-impl-1.1-qti".
This is to serve 1.0 clients with the existing 1.0 getService call.
1.1 AOSP clients get the 1.0 instance and cast it to 1.1, and use
1.1 APIs (on virtual a/b enabled devices).
This makes use of the AOSP's libboot_control helper library to call
the 1.1 APIs to read/write to misc partition.
