QCommandLineParser: add parsing mode for options after arguments

The new mode, ParseAsPositionalArguments, allows to interpret
"application argument --opt" as having two positional arguments,
"argument" and "--opt".
This mode is useful for executables that aim to launch other executables
(e.g. wrappers, debugging tools, etc.) or who support internal commands
followed by options for the command. "argument" is the name of the command,
and all options occurring after it can be collected and parsed by another
command line parser, possibly in another executable.

[ChangeLog][QtCore][QCommandLineParser] Add parsing mode for options
after arguments, to allow treating them as more arguments.
