FFI TypeError. static structs require parameters #28112

Version: Deno 2.1.9

Reproduce:

Deno.dlopen("", { x: { type: { struct: [] } } })

outputs:

Uncaught TypeError: missing field `parameters`
    at new DynamicLibrary (ext:deno_ffi/00_ffi.js:456:42)
    at Object.dlopen (ext:deno_ffi/00_ffi.js:562:10)
    at <anonymous>:1:27

If static structs aren't supported, the error is in the typing of Deno.dlopen.

It's possible to workaround this by specifying type : "pointer" and manually creating an ArrayBuffer from the memory
