Support generation of component targets for Mojom C++ bindings
This allows developers to force the mojom GN template to emit a
component target for C++ bindings rather than a source_set and updates
some existing uses of the export_class_attribute etc parameters to use
explicit component generation instead.
This is a step towards using mojom component targets by default, but
that is currently impossible without additional GN support.
