Update Flutter 3.38.3 (#19)

- flutter#172588 has been included in
3.38. So it excludes that was applied in 3.35.3.
- Added the `--no-lto` gn option.
- `flto` for linux was added but it have been disabled in Flutter CI due
to build performance issues.

- If we want to apply the flto option, we need a container with an
updated toolchain.
