Create Visual Studio Options Documentation

[donnie-msft]

Fixes: NuGet/Home#14039
Fixes: NuGet/Home#14506

• Creates a new Visual Studio Options page listing each NuGet settings page.
• Cross-references other NuGet documentation to point to the Options page to minimize duplicate instructions and noise.
• Removed old screenshots and replaced with new screenshots of the Unified Settings UI.

Note that the F1 Keyword help linkage is not currently supported in Unified Settings. However, I went ahead and moved that metadata to the new file in case it does light up in the future.

Preferably, use the Preview URLs below.
Alternatively, here's the Rendered nuget-visual-studio-options.md (New File). Please also review the changes to companion docs outside of this file.
