MDEV-36235 Incorrect result for BETWEEN over unique blob prefix

Browse Source 
Disallow range optimization for BETWEEN when casting one of the arguments
from STRING to a numeric type would be required to construct a range for
the query.

Adds a new method on Item_func_between called can_optimize_range_const
which allows range optimization when the types of the arguments to BETWEEN
would permit it.
