Copy Installer Pipeline ymls

[ellahathaway]

Related to dotnet/source-build#4357

This is the first step in migrating unified-build and source-build installer pipelines to sdk pipelines.

This PR copies files in installer/eng/pipelines to sdk/eng/pipelines. Also copies installer/eng/vmr-sync.sh and installer/eng/vmr-sync.ps1.

This step allows us to (in future steps):

1. Create the public pipelines. The public pipelines depend on the ymls being in the public repo.
2. Update ci.yml and pr.yml to reference sdk/eng/pipelines.

@ViktorHofer - I've left out the sync logic and related ymls from this PR since I wasn't sure if they would impact builds. Let me know if you think I should include them. Thanks in advance.

Just as a general question, do we feel strongly about including history for these files? I'm not sure tbh. cc @MichaelSimons @mmitche

Yeah, we need everything and the files shouldn't impact main until we actually create pipelines, link to the YML and run them.

I don't feel strongly about having the history in sdk.

This is a straight copy without any modifications, right?

Correct. I can make the modifications for installer to sdk if we want. Almost all of them are related to the syncing.

Let's do the edits in another PR to keep this focused on just the code move. Feel free to merge.
