Implement building the repo for multiple configurations and architectures with a single command on Windows. (#33295)

* Implement building the repo for multiple configurations and architectures with a single command on Windows.

* Use -Command instead of -File to invoke pwsh build script.

* Run all builds and output which builds failed at the end (if any)

* Update help output.

* Prepend argument list with architecture args instead of appending so as to allow scripts to override them with MSBuild arguments.

* Fix typo.
