feat: hide several --unstable-* flags (#25378)

This commit hides following unstable flags:
- `--unstable-ffi` (the API is now stable)
- `--unstable-webgpu` (this API is now stable)
- `--unstable-fs` (no more unstable APIs)
- `--unstable-byonm` (BYONM is on by default)


The flags are still parseable, but they are not used. Concrete cleanup
will be done in a follow up PR.
