[arm64] Build NDK with PAuth and BTI
This change adds a new arch named "armv8-a-branchprot". The new target is no different from the usual "armv8-a" variant except it has the compiler flag "-mbranch-protection=standard" set. With this flag compiler emits Armv8.3-A Pointer Authentication and Armv8.5-A Branch Target Identification instructions. All of these instructions are in the hint space; therefore devices which do not support any of these extensions would execute them as NOPs. In terms of directory structure there is no change in the output of build/soong/scripts/build-ndk-prebuilts.sh script. Test: build NDK prebuilts Change-Id: Ie52ccba5653fbf567f0b7ca312d8a8e71602ad06
