ui/cocoa: add option to disable left-command forwarding to guest

Browse source 
When switching between guest and host on a Mac using command-tab the
command key is sent to the guest which can trigger functionality in the
guest OS. Specifying left-command-key=off disables forwarding this key
to the guest. Defaults to enabled.

Also updated the cocoa display documentation to reference the new
left-command-key option along with the existing show-cursor option.
