Remove (Open)Watcom support.

This compiler is not being developed since several years and almost certainly
can't be used to build the current wxWidgets sources anyhow, so remove all
support for it, including a lot of extremely ugly workarounds for its bugs
with template functions.

------------------------
-
-If odbc32.lib isn't supplied with your Watcom C++ compiler,
-you can use this one. If you find that the ODBC API changes
-and you get some unresolved SQL... references, add items to
-odbc.txt, put odbc32.dll in this directory, and then call
-makeit.bat in order to regenerate odbc32.lib.
-
-If you already have a suitable odbc32.dll, change the reference
-in src\makewat.env to the one you wish to use.
