rust: macros: remove THIS_MODULE static from module!

Browse Source 
All users have been migrated to `ModuleMetadata::THIS_MODULE` const or
`this_module::<LocalModule>()` helper. The `static THIS_MODULE`
generated by the `module!` macro is no longer referenced anywhere,
so remove it to avoid having two sources of the same `ThisModule`
pointer.
