[glew] Fix build with CMake 4.0

[chrismile]

This PR fixes the compilation of the GLEW port with CMake 4.0, which removed compatibility with versions of CMake older than version 3.5 (see https://cmake.org/cmake/help/v4.0/release/4.0.html#deprecated-and-removed-features). I have tested on CMake 4.0.0 RC2 that the build process no longer fails with the proposed changes.

While this issue was fixed in the upstream repo some time ago, vcpkg uses the sources of the last release, which has been created a few years ago. portfile.cmake makes this statement why using the code from the main branch of the upstream repo is not directly possible:

# Don't change to vcpkg_from_github! The sources in the git repository (archives) are missing some files that are distributed inside releases.
# More info: https://github.com/nigels-com/glew/issues/31 and https://github.com/nigels-com/glew/issues/13

... so I think the solution proposed by this PR using a patch is the best solution for now.

• Changes comply with the maintainer guide.
• SHA512s are updated for each updated download.
• The "supports" clause reflects platforms that may be fixed by this new version.
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

IIUC you could use CMAKE_POLICY_VERSION_MINIMUM instead of adding a patch.

Yes, that should probably also work, but I had the impression adapting cmake_minimum_required would be more consistent with the vcpkg codebase. A search for CMAKE_POLICY_VERSION_MINIMUM in the ports directory gave me no results, while there seems to be many patches with entries for cmake_minimum_required. Some examples for this are:

• parmetis/build-fixes.patch
• godot-cpp/packagable.patch
• ... (in total 27 patches for changing the value used for cmake_minimum_required)

This variable comes with CMake 4.0, so you can't expect examples.

@dg0yt Feel free to tell me in case I should change using a patch to using -DCMAKE_POLICY_VERSION_MINIMUM=3.5. Probably this will generate a warning when users have older versions of CMake (if I remember correctly, CMake gives a warning when unused/unsupported arguments are detected), but if that's your preferred solution, I'm of course fine with adapting the PR.
