Remove the need for rust-mozjs to use unstable Rust features #18875

  1. Remove unused feature flag

  2. Give up on NonZeroUsize memory layout optimization with unstable feat… 

    …ures.

I’m not confident of the implications regarding variance, dropck, struct
aliasing, etc. when this is extended to generic `*const T` and `*mut T`.

Release builds should use `unstable` to enable other optimizations anyway.

  3. Replace NonZeroU32 and NonZeroUsize with a generic NonZero 

    The API is identical to core::nonzero::NonZero
