[CMakeRC] support CMake 4.0 (#1632)

Because the version of CMakeRC that vcpkg depends on is so old, it has 
a `cmake_minimum_required(VERSION 3.3)`; this is not valid now that
CMake 4 has come out.

There are three options for fixing this:

- just add a maximum version in a patch
- start using a later version; unfortunately, this is not possible
  without changing how CMakeRC is downloaded, since the last tagged
  version of CMakeRC is from 2018
- Just pull CMakeRC into the tree. Given that the last tagged version is
  from _seven_ years ago, this seems entirely reasonable, but I didn't
  want to do that work without someone telling me that that was what
  they wanted.

I chose the first option since it's the simplest one.
