 Add `-c XY` to create a generic Cartesian coordinate system to `grass`
 command (compare options in the current CLI to wxGUI Location Wizard).

 The current `--help` lists `-c` (with nothing) as a valid syntax which is
 useful for creating new mapset (as opposed to new location) and it was
 already there for `grass6`.

 `--tmp-location` with `-c` (with nothing) now actually creates XY
 location, but that's more a side effect than an intention. Being explicit
 and require `XY` seems much safer.

 Usage would look like:

 {{{
 Usage:
   grass75 [-h | -help | --help | --h] [-v | --version]
           [-c | -c geofile | -c EPSG:code[:datum_trans] | -c XY]
           [-e] [-f] [-text | -gtext | -gui] [--config param]
           [[[GISDBASE/]LOCATION_NAME/]MAPSET]
   grass75 [FLAG]... GISDBASE/LOCATION_NAME/MAPSET --exec EXECUTABLE
 [EPARAM]...
   grass75 -c [geofile | EPSG | XY] --tmp-location --exec EXECUTABLE
 [EPARAM]...
 }}}

 This is not limited to `-c` only but potentially influences also `--tmp-
 location` which may or may not require `-c` (see #3585).

 Because of how `--tmp-location` now works, this would change the
 interface, hence blocker for 7.6 (it should be resolved before release to
 keep the interface clean).
