Mojo Bindings: Put typemap files in the build dependency tree

This ensures that any typemap configuration files used to configure an
internal type-mappings-generator target are included in that target's
set of inputs. Otherwise this dependency only comes in the form of
read_file() calls made outside of any target scope, and GN fails to
deduce the effect this has on mojom targets.
