[vcpkg] Set CMP0174 NEW

[dg0yt]

Fixes #41999.

This PR intentionally forces the new behavior:

• The relevant spot in vcpkg scripts actually expect the new behavior.
• Old behaviors are deprecated. vcpkg will eventually adopt the new behavior.
• No change for users with CMake < 3.31.
  Ports outside vcpkg CI do not need updates unless they really rely on the deprecated behavior AND are used with CMake >=3.31.

Tested locally (with some ports). CI still uses at 3.30.
