Call __wasm_call_ctors before calling any exported functions

This should be done by wit-bindgen, but it only does it for the Rust
code generation.
https://github.com/bytecodealliance/wit-bindgen/blob/c6dc35fb6966572cae64f2720dd08cc1bcfd0f9e/crates/guest-rust/src/lib.rs#L46

This is a workaround to make sure that the constructors are called before
calling any exported functions manually.
