Continue the convergence between LLVM dialect and built-in types by replacing the bfloat, half, float and double LLVM dialect types with their built-in counterparts. At the API level, this is a direct replacement. At the syntax level, we change the keywords to `bf16`, `f16`, `f32` and `f64`, respectively, to be compatible with the built-in type syntax. The old keywords can still be parsed but produce a deprecation warning and will be eventually removed.
