Adding Azure DevOps YAML build file

[mcumming]

• Build master, release branches commit and PR's
• Processes translations from localization pipeline
• Update README to point at new pipeline
• Added github action to auto-create PR when trnaslations are pushed on loc branch.

Fixes: https://dev.azure.com/devdiv/DevDiv/_workitems/edit/1052929

@mcumming So is this change to automate pulling in the translations?

Are there now 2 builds going on? One for translation over on https://dev.azure.com/xamarin/public/_build?definitionId=50 and the other on https://devdiv.visualstudio.com/DevDiv/_build/latest?definitionId=5330 or does this means we only have 1 build happening now?

I'm just trying to understand what we are trying to achieve as I have no context for this PR.

This will replace the existing build definition which is private with one that is publicly accessible, and includes translation processing.

@mcumming Any ideas about the failing build?

LGTM. I'd like another pair of eyes on it, if that is ok, before pulling it in.
