Snapp Public AOSP Local Manifest

This manifest adds a number of targets to an AOSP build. To make use of this you should;

1. Init your repo with the appropriate URL and branch (e.g. repo init -u https://android.googlesource.com/platform/manifest -b android-platform-15.0.0_r1 --git-lfs).
2. Checkout this repo into the local manifests area (e.g. git clone https://github.com/snappautomotive/firmware-local_manifest.git .repo/local_manifests -b android-15).
3. Perform a repo sync (e.g. repo sync)
4. Use one of the additional targets (e.g. snapp_car_x86_64-ap3a-userdebug) . . .
5. Profit!
