Add short flags to options

[luxploit]

Is your feature request related to a problem? Please describe.

Currently in XMake when I add an option like for example game, I must always use --game= when configuring it.

In my case, configuring my project would look something like this at the moment: xmake f -a amd64 -m debug --game=portal2

Describe the solution you'd like

It would be pretty great if option could add an extra argument that sets the short flag so for example:

option("game", "g")

where g is the short flag and could then be set via the cli using -g.

Configuring my project would then be shortened to just: xmake -f -a amd64 -m debug -g portal2

This may increase the chance of configuration name conflicts. Maybe I will consider this in the future, but it is not a priority at the moment.
