[PATCH v6 1/5] rust: module: add type `LocalModule`

[Danilo Krummrich <dakr@kernel.org>]

The `LocalModule` type is the type of the module created by `module!`,
`module_pci_driver!`, `module_platform_driver!`, etc.

Since the exact type of the module is sometimes generated on the fly by
the listed macros, provide an alias.

This is first used by the `module_firmware!` macro.
