Subject: [PATCH] fix(spanner/spansql): allow all hash functions

The `spansql` package is quite useful for parsing and managing schemas,
however, with the addition of `CHECK` constraints to the spanner DDL,
the full set of SQL functions can now appear in schemas.

Fill in the missing Hash functions to support their use.
