Remove the duplicate implem of hash codes for numbers.

Previously, there were two separate implementations of hash
code for boxed number classes:

* One in Statics, used by the codegen of case class methods.
* One in ScalaRunTime + BoxesRunTime, used by everything else.

This commit removes the variant implemented in ScalaRunTime +
BoxesRunTime, and always uses Statics instead. We use Statics
because the one from ScalaRunTime causes an unnecessary module
load.

The entry point ScalaRunTime.hash() is kept, as deprecated,
for bootstrapping reasons.
