Move "build in ACR" command to ACA extension

[bwateratmsft]

The Azure Container Apps extension is soon adding a command to build images in ACR. Using this would allow us to remove several Azure packages as dependencies, improving load time and reducing bundle size.

TODO: do we want to remove the command entirely, or leave in a soft entry point like we currently have with "Deploy to ACA"?

Will this require having an ACA dependency to simply deploy to ACR?

No, the only thing I'd like to move is the "Run as task in Azure" / "Build image in Azure" feature. Local build and push, along with the other ACR features (repo browser essentially) should definitely stay in the Docker extension.

Let's seperate this into an NPM package that ACA and other extensions can leverage

Moving to future as ACA still requires the Docker extension for authenticating and getting subscription/registry information.
