Add M1 build agent to build-toolchain.yml (#3463)

* Add M1 build agent to `build-toolchain.yml`

* Install cmake

* Install homebrew

* List homebrew

* Modify PATH

* Don't attempt to select Xcode on M1

* Set Xcode path via `DEVELOPER_DIR`

* Avoid setting `brew` path

* install cmake

* Update build-toolchain.yml

* Clean build directory to avoid module and compiler version mismatch

* Control whether to run tests or not on ci script
