brew is failing with "Error: undefined method 'first' for nil" when trying to upgrade itself. We already use Java 11 on other platforms, and it is already available on the Kokoro machines. We swap to download Maven just like we do for Linux, so then we can avoid brew entirely. However, the pre-installed Java is an arm build whereas the brew install was x86. So now the examples try to use protoc-gen-grpc-java-1.82.0-SNAPSHOT-osx-aarch_64.exe which don't exist because we used the default ARCH of x86_64. So now we also need to swap the primary platform on OS X to aarch_64 and copy the x86_64 binaries from that.

CC @shivaspeaks, feel free to review, since you worked on the universal binaries
