gh-65701: document that freeze doesn't work with framework builds on macOS (GH-113352)

* gh-65701: document that freeze doesn't work with framework builds on macOS

The framework install is inherently incompatible with freeze. Document
that that freeze doesn't work with framework builds and bail out
early when trying to run freeze anyway.

(cherry picked from commit df1eec3dae3b1eddff819fd70f58b03b3fbd0eda)
