[release/5.0] Clean out Ubuntu 16.04 testing

- cherry-pick of #32894

* Clean out Ubuntu 16.04 testing
  - use Ubuntu 18.04 agents for testing in Docker containers on Helix
  - also move to supported version of Fedora

* Support added `msbuild` arguments in RunHelix.ps1
  - bring in part of 0551cef (#32554)
  - no reason to maintain major differences from main version of script
    - slight difference is we still test on Windows.10.Amd64.Open by default here

nits:
- clean up a few old mentions of Centos and Fedora testing
- fix `%(Platform)` metadata for OSX `@(HelixAvailableTargetQueue)` items
- pick up a small bit of the master -> main renaming improvements
- use `[switch]` instead of `[bool]` in RunHelix.ps1 parameters
