Watcom: Simplify compiler version detection (#11866) 

Since commit c198730b (Detect Watcom compiler version with its id,
2011-12-07) the CMAKE_(C|CXX)_COMPILER_VERSION variables are set for the
Watcom compiler.  Use these in Windows-wcl386.cmake to set the old
WATCOM1* version variables.  This avoids using the old EXECUTE_PROCESS
command which failed due to extra quotes anyway.
