SvxNumberFormat::nAbsLSpace should have a larger type

...as is seen when executing CppunitTest_sd_filters_test with Clang's new
-fsanitize=implicit-conversion (see below).  The next larger natural choice
after short is sal_Int32, and some of the code calling GetAbsLSpace actually
already supported the value to be as wide (but not wider than) sal_Int32; code
calling GetAbsLSpace that expected the value to be no wider than short has
either been adapted or at least been marked with a TODO.  (Other choices could
have been sal_Int64 or long.)

Some dependent function's parameter types have also been changed accordingly.
