Revert "Put basic impls for f16 and f128 behind cfg(not(bootstrap))"

This reverts commit 049a917535.

The resolution to <https://github.com/rust-lang/rust/issues/123282> is
that the `f16`/`f128` regression in the beta compiler was fixable
without a revert, so the commit adding `#[cfg(not(bootstrap))]` is no
longer useful (added in
<https://github.com/rust-lang/rust/pull/123390>).

Revert this commit because not having these basic impls bootstrap-gated
simplifies everything else that uses them.
