Correct platorm reach for the Official build (#21310)

* Correct platorm reach for the Official build

Does the following:

1. Sets up a ci rule for master and a pr rule for master
2. Corrects the OSX queues
3. Corrects ubuntu internal queue
4. Converts all linux jobs to build using containers
5. Only runs official builds on: Pri1, release, bringing us to parity with old process
6. Fixes centos build-test
7. Adds a super-annoying groupname tag that avoids name mangling.

* make sure we only add triggers for internal builds

* Fix syntax

* Missing :

* Remove pr/ci

* Fix internal queue name

* Correct Public/internal choices.

* Add crossgen as well

* Correct indentation

* Correct checked pri1 tests

* Address pr feedback

* Add todo comments
