Remove this and the export_depenedent_settings value. If you have these settings
on the generation target (this one), the net result (because the GYP rules are
awful) is that anyone who depends on password_manager_content_mojo_bindings will
inherit their own dependency on the url bindings static library, hence the
multiple definitions.

Instead you want to add dependencies and export_dependent_settings in this
target, and you should use the url_mojom target here rather than
url_interfaces_mojom.

This should make the linker happy.
