Recommend Windows users to use winget configure

Is your feature request related to a problem? Please describe

Currently Windows toolchain installation involves multiple steps, which is over-complicated for new users or developers from other platforms. We can both make the step simpler and more robust.

Describe the solution you'd like

Windows Package Manager includes WinGet Configuration tool in its latest release, which allows users to set up the required environment from a single configuration file (written in YAML), with advanced features like Developer Mode detection and control flow. We can provide the configuration, and to ensure all tools and functionalities are properly set up for Swift.

Describe alternatives you've considered

Either keep the existing way, or using a CMD/PowerShell script. Neither batch script nor PowerShell is as clear as the configuration file, and it is potentially dangerous to run a remote script which we shouldn’t promote.

Awaiting microsoft/winget-cli#3554 which may help reduce the setup to a single command

Now that the feature is in preview, and it seems to solve the multiple problems we've had before (including setting SeSymbolicLinkPrivilege automatically, where @compnerd may be interested). However, I would like to see if there's opportunity for Swift.org to provide "dynamic" (or configurable in some way) WinGet configuiration files so that users with all kinds of need can just copy and install with just two clicks and a single command run.

Maybe there could be an online meeting on this?
