Vadim Zeitlin 49b8d79c87 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.
