Add missing TYPE_CODE_* constants to Python

A user noticed that TYPE_CODE_FIXED_POINT was not exported by the gdb
Python layer.  This patch fixes the bug, and prevents future
occurences of this type of bug.

-       Regardless of the language, GDB represents multidimensional
-       array types the way C does: as arrays of arrays.  So an
-       instance of a GDB array type T can always be seen as a series
-       of instances of T->target_type () laid out sequentially in
-       memory.
-
-       Row-major languages like C lay out multi-dimensional arrays so
-       that incrementing the rightmost index in a subscripting
-       expression results in the smallest change in the address of the
-       element referred to.  Column-major languages like Fortran lay
-       them out so that incrementing the leftmost index results in the
-       smallest change.
-
-       This means that, in column-major languages, working our way
-       from type to target type corresponds to working through indices
-       from right to left, not left to right.  */
