spanner/spannertest: initial support for ALTER TABLE ... ALTER COLUMN

This permits converting between STRING and BYTES, including changing
their length limits. It doesn't actually validate the latter (we don't
track or enforce it elsewhere), but does rewrite the stored data for the
former.

Fixes #1809.
