`VCPKG_TRACE_FIND_PACKAGE` produces logs although `CMAKE_DISABLE_FIND_PACKAGE_` is set

**Repro**

Using port `sdl2`:

- Set `-DCMAKE_DISABLE_FIND_PACKAGE_Git=ON` and `-DVCPKG_TRACE_FIND_PACKAGE=ON` in `OPTIONS`
- Notice that the configure logs still contain `find_package(Git )`

**Expected behaviour**

Don't see `find_package(Git )` in the logs.
It would make it easier to see if finding a certain package is actually disabled or not - especially if we would add a post build check for optional calls to `find_package`.
