Refactor GSI BoardConfig.mk

The patch modifies the Legacy GSI to use BoardConfigGsiCommon.mk
instead of board config treble-common*.mk, and delete these
treble-common*.mk files.

After the patch, the GSI common board configs are in single file
BoardConfigGsiCommon.mk

The patch also includes:

- Moving `TARGET_COPY_OUT_VENDOR := vendor` to
  BoardConfigGsiCommon.mk, because GSI always contains no vendor
  contents.
- Configure the binder interface bitness explicitly.
- Unify the structure of each BoardConfig.mk.

Bug: 122282239
Test: compare the out folder between with and without the patch
Test: output files are all the same

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
