Updated protobuf gradle plugin version to 0.8.13. Fixed Android Kokoro's memory issue by forcing to use a new Gradle daemon for building the previous commit.
This resolves#5523
While bumping `com.android.tools.build:gradle:3.1.2` to `3.3.0`, some other plugins/artifacts/maven repo/buildscripts have to be updated:
- gradle (wrapper) need to upgrade to 4.10.x
- protobuf gradle plugin need to bump a version compatible with gradle version.
- need add `google()` and `jcenter()` repos for android (otherwise `com.android.tools.build:aapt2:3.3.0x` and `trove4j` will not be found resp.)
- need to accept license for Android "build-tools;28.0.3" in kokoro env.
We always want to use a consistent version of protobuf; avoid the need
for the caller (which may be a person running the script) to specify the
version.
Since 4369e8cd the --include-build just opens us up to trouble with
accidentally building the protoc plugin. Since we're going to do a
./gradlew install anyway, let's just wait until after that point for
building cronet.
This sort of problem was experienced while developing #4369.
