Genericize setinputsizes and support pyodbc
Reworked the "setinputsizes()" set of dialect hooks to be correctly
extensible for any arbirary DBAPI, by allowing dialects individual hooks
that may invoke cursor.setinputsizes() in the appropriate style for that
DBAPI. In particular this is intended to support pyodbc's style of usage
which is fundamentally different from that of cx_Oracle. Added support
for pyodbc.
Fixes: #5649
