fix(js): use FixedArray at JS FFI boundaries returning arrays

`Array[T]` is represented as a `{buf, len}` struct on the JS backend,
while `FixedArray[T]` is a raw JS array, so returning a JS array from an
FFI declared as `-> Array[String]` handed MoonBit a malformed value.
This is what the `-deprecated` warning on `Array` in JS FFI is about.

- `encoding/utf8`: `decode_utf8_js` now returns `FixedArray[String]`.
- `env`: `get_env_vars_array_internal` now returns `FixedArray[String]`.
- `env`: split `get_cli_args_internal` into an FFI returning
  `FixedArray[String]` plus a wrapper converting to `Array[String]`,
  since the public `env.args()` returns `Array[String]`. This fixes an
  actual bug: `env.args()` was returning a raw JS array typed as `Array`.

Clears the last three deprecated-FFI warnings from `moon check --target all`.
