Mike Bayer 99b292c5c5 Use cx_Oracle.FIXED_NCHAR for sqltypes.NCHAR ...

The :class:`.sqltypes.NCHAR` datatype will now bind to the
``cx_Oracle.FIXED_NCHAR`` DBAPI data bindings when used in a bound
parameter, which supplies proper comparison behavior against a
variable-length string.  Previously, the :class:`.sqltypes.NCHAR` datatype
would bind to ``cx_oracle.NCHAR`` which is not fixed length; the
:class:`.sqltypes.CHAR` datatype already binds to ``cx_Oracle.FIXED_CHAR``
so it is now consistent that :class:`.sqltypes.NCHAR` binds to
``cx_Oracle.FIXED_NCHAR``.
