Examine Yarn.MSBuild for performance issues

[dougbu]

• source is in https://github.com/natemcmaster/Yarn.MSBuild
• according to @mmitche this SDK is a significant source of extraneous logging and slowdown in the aspnetcore-ci pipeline
  • @mmitche please some details on what you've seen to this issue
• in Disable Yarn warnings on CI builds for restore and Blazor WebAssembly projects #22703 (comment), @javiercn noted we can't use the task invocation to suppress specific warnings and this potentially hides issues we introduce in the future

@Pilchie we don't really have yarn expertise on the build v-team. Should we track this in DoI?

[Pilchie]

@mkArtakMSFT - can your team take a look and see what can be done to help speed up our builds here?

[javiercn]

This might be a thing we can leverage to run yarn install once instead of N times.

We may be able to do something here but I defer to @mkArtakMSFT and his team on whether the larger org ever gets to it. @dotnet/aspnet-build likely will not have time to do more than review the good work @mkArtakMSFT's team does.

There isn't anything specific here to act on now, instead we should brainstorm and come up with ways to speed this up, which we can do any time in the future too. Closing for now, as we have no plans to do such investigation now.
