Function wasmtime_runtime::wasmtime_init_finish

#[no_mangle]
pub extern "C" fn wasmtime_init_finish(vmctx: &mut VMContext)

Assuming EnsureEagerProcessSignalHandlers has already been called, this function performs the full installation of signal handlers which must be performed per-thread. This operation may incur some overhead and so should be done only when needed to use wasm.
