…editor) This is consistent with `xatlas_unwrap`, which isn't enabled in non-editor builds and the Android editor either. There is currently no way to use the lightmapper in a non-editor build anyway, as it doesn't expose any methods (and even if there was, there would be no way to perform UV2 unwrapping in the exported project). This reduces binary size of a stripped Linux x86_64 export template build by ~164 KB. This also moves the PrimitiveMesh texel size project setting so that it's defined when the module is disabled, and adds a property hint to it.

In the future, if we decide to make this functionality available in non-editor builds, it should also be made available with
xatlas_unwrapas a build-time option (similar to #73003).I tested this PR in a project with existing baked lightmaps and it works as expected (no errors, it renders correctly).
lightmapper_rdmodule is included in export templates, even though it can't be used #72544.
