Avi Kivity ea901fdb9d cql3: expr: fold null into untyped_constant/constant ...

Our `null` expression, after the prepare stage, is redundant with a
`constant` expression containing the value NULL.

Remove it. Its role in the unprepared stage is taken over by
untyped_constant, which gains a new type_class enumeration to
represent it.

Some subtleties:
 - Usually, handling of null and untyped_constant, or null and constant
   was the same, so they are just folded into each other
 - LWT "like" operator now has to discriminate between a literal
   string and a literal NULL
 - prepare and test_assignment were folded into the corresponing
   untyped_constant functions. Some care had to be taken to preserve
   error messages.

Closes #12118
