There is one: font-lock-constant-face. At least, that's what Ada mode
uses for numeric literals.

I agree the major mode should apply the face to the literals, rather
than having some minor mode do it.

If there is some language that does not yet have a major mode, it is
very easy to tell font-lock to highlight the keywords and literals.
