Add `f16` and `f128` to `tests/ui/consts/const-float-bits-conv.rs`

[tgross35]

This file is only f32 and f64: https://github.com/rust-lang/rust/blob/a73bc4a131d94eba633c4c572a28e0bf94a67530/tests/ui/consts/const-float-bits-conv.rs, but we should add the other float types to this test.

The change should wait for #128598 since that changes some of these semantics (this PR is almost merged).

There are probably a handful of tests that only check f32 and f64 but could use updates with the new types.
