Add Azure Pipelines configuration

Huge thanks to ＠johnterickson and ＠willsmythe for writing the initial config! :heart:
I applied some changes to the initial config and disabled most of the builders since we're not going to run all of them during the initial step for the evaluation.

[More details about our plans for the Azure Pipelines evaluation.](https://internals.rust-lang.org/t/update-on-the-ci-investigation/10056)
