wasm: use module_property instead of global(“Module”)

Browse Source 
Depending on build options, the module can have a different
name, or be a non-global object. We were already using
module_property in many places, but some were missing.

In the case of the clipboard code, there is actually
no need to export all of the C++ functions to JavaScript
and then resolve them from the module; instead call them
directly.
