c-api: Add a way to get type of wasmtime_module_t (#3959)

Browse Source 
My previous PR at #3958 accidentally removed the only way to get type
information from a `wasmtime_module_t`, so this commit re-adds methods
back in to continue to be able to get import/export information from a
compiled module.
