Generate Android.bp from multiple gn descriptions

With the introduction of ABI-specific build targets (zlib), the script generate_android_bp.py needs to be updated to consume ABI-specific gn descriptions and generate ABI-specific build rules for each target. The roll_aosp.sh script was updated to generate ABI-specific gn descriptions for each: arm arm64 x86 x64 Bug: b/160727922 Test: Manual script execution and building in AOSP Change-Id: I459b388176f8fcc010f9f5668535d941b931cdd4 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2285272 Commit-Queue: Tim Van Patten <timvp@google.com> Reviewed-by: 's avatarGeoff Lang <geofflang@chromium.org>
