Get the windows kits root from the registry value "HKLM\SOFTWARE\Microsoft\Windows Kits\Installed Roots" @KitsRoot10

[JaynieBai]

Fixes #6090

Context

See here:

msbuild/src/Tasks/Microsoft.Common.CurrentVersion.targets

Line 2348 in ec6ed83

$(MSBuildProgramFiles32)\Microsoft SDKs\Windows Kits\10;$(MSBuildProgramFiles32)\Windows Kits\10
It's always looking for the Win10 SDK root under program files ($(MSBuildProgramFiles32)\Windows Kits\10). It should instead get the root from the registry value "HKLM\SOFTWARE\Microsoft\Windows Kits\Installed Roots" @KitsRoot10

Changes Made

Get the root from the registry value "HKLM\SOFTWARE\Microsoft\Windows Kits\Installed Roots" @KitsRoot10 with $([MSBuild]::GetRegistryValueFromView('HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Kits\Installed Roots', 'KitsRoot10', null, RegistryView.Registry32, RegistryView.Default))

Testing

Couldn't install the windows SDK10 in non-default driver in the pipeline machine. So, test it locally.

Notes

[KalleOlaviNiemitalo]

AFAIK FEATURE_WIN32_REGISTRY is only defined when targeting .NET Framework, so with this PR, dotnet msbuild on Windows would no longer be able to locate the Windows kits.

Also, reserving the WindowsKitsDirectory property name might conflict with a property already being used in a project. MSBuildWindowsKitsDirectory would be safer as a name.
