move test tools into vendor-bin

[brettmc]

To reduce (hopefully, eliminate) the situations where our testing tools have conflicting dependencies, use bamarni/composer-bin-plugin to manage them as separate vendored dirs. Update Makefile and github actions to use the self-contained versions. Remove the dependencies from root composer.json Rejigger dockerfile to add opcache, and some config required for latest version of grpc

Replace: #1300
