Makefile: Generate single-quoted object lists for Watcom

Drop the CMAKE_NO_QUOTED_OBJECTS internal variable from the Makefile
generators.  The underlying problem is with the Watcom linker, not with
WMake.  The Watcom linker wants object files to be single-quoted.  Add
<LINK-RULE>_USE_WATCOM_QUOTE platform information variables to tell the
generators to use Watcom-style single quotes for object files on link
lines.

On Windows, Watcom uses the GetCommandLine API to get the original
command-line string and do custom parsing that expects single quotes.
On POSIX systems, Watcom approximates the original command line by
joining all argv[] entries separated by a single space.  Therefore we
need to double-quote the single-quoted arguments so that the shell does
not consume them and they are available for the parser to see.
