fix(runtime-core) Share the definition of Trampoline across all the backends.

This patch updates all the backends to use the definition of
`Trampoline` as defined in the `wasmer_runtime_core::typed_func`
module. That way, there is no copy of that type, and as such, it is
easier to avoid regression (a simple `cargo check` does the job).

This patch also formats the `use` statements in the updated files.
