Perhaps we just set has_large_values to be false for float16?

I know we disallow float16 in Index and in many places upcast float16 inputs to float32/float64. I think eventually we should deprecate float16 supports everywhere

Thanks @mroeschke - searching through the issues I see now that it was never really supported in pandas. I'll remove it from the docs in #60987.
