Make the `long double` overload if AbslHashValue a template to avoid invalid
conversions with implicit operators.

This overload was never meant to capture anything other than `long double` and any current caller to it that wasn't a `long double` is potentially a bug.
In particular, any type with an implicit `bool` conversion is calling this
overload instead of trying to find a hash<> specialization, thus causing
pretty bad hash behavior.
