Subject: [PATCH] Add dependency on Windows SDK CIPD package
 (flutter/engine#26003)

We now build against a specific Windows SDK rather than whatever happens
to be installed on the host machine.

This also rolls the buildroot to include change
https://github.com/flutter/buildroot/pull/448, which generates the WinRT
headers from the CIPD Windows SDK.

This also rolls an updated version of cppwinrt that includes supports
for long paths.

This also re-enables the UWP builder.
