[gn] Update to current version

[bold84]

Describe the pull request

While trying to update the Skia port, I found that it doesn't build with vcpkg's version of GN. It seems to be too old.

This change may require updates to ports that use gn.

So, how am I supposed to do this?
Updating the Skia port to a newer version requires updating gn. But it seems that the old gn isn't compatible with the new Skia gn files.
Just one PR for all of it?
