Add bazel php:release target for PECL tgz using generated package.xml (#10845)

* Add bazel php:release target for PECL tgz using generated package.xml

* move targets from php/ext/google/protobuf to php packages since this breaks dist_files and add utf8 license file

* Remove package.xml form Makefile.am

* add files to Makefile.am
