cmMakefile: Add filename context to ExpandArguments.

The cmListFileArgument currently stores a FilePath for use in this
method.  The filename is the same as the CMAKE_CURRENT_LIST_FILE,
except if executing a macro or function defined in another file.

Set the context filename when expanding the arguments of macros and
functions using the filename recorded when defining the prototype.
