core: split print_float into print_float and print_float_attr

[jorendumoulin]

To allow for printing floats that are not FloatAttrs but the type is known (such as for bytes-backed DenseIntOrFPElementsAttrs), this changes the print_float implementation to accept raw floats with a known type.

Is there a way we can add a test case to this PR?

I think there are some other places where we print floats manually but did know the type, however it'd be fine to catch these later.
