De-duplicated code to generate PHP protos and install phpunit. (#7605)

* De-duplicated code to generate PHP protos and install phpunit.

* Removed all references to generate_php_test_proto.

* Replaced with internal_build_cpp.

* Make Timestamp::__construct() static to avoid conflicts with MongoDB.

* Replicated PHPUnit versions and added new script to Makefile.am.

* Fixed filename in Makefile.am.

* Disabled test that SEGV's on macOS.

* Removed extraneous "set -e".

* Make sure generate_protos.sh happens on every test path.

* Removed stray '$' chars.

* Added proper support for aggregate_metadata tests. But now I get a stack overflow.

}

* Fixed and verified metadata aggregation testing.
