Add implicit F8 conversions

Adds implicit conversions between F8 types and `float`, `half`, and `bfloat16`. This allows using the `std` math functions for the F8 types as easy as if they were `float` or `bfloat16`. Note that `bfloat16` already has an implicit conversion to `float`, so it already has good ergonomics. PiperOrigin-RevId: 669054332
