Original change's description:
> [TabGroups] Default Enable TabGroupShortcuts Feature
> 
> Default enables the TabGroupShortcuts feature on ToT in preparation for
> launch.
> 
> Mac: The accelerators are omitted in accelerator_table.cc since they
> are already added in global_shortcuts_mac.mm
> 
> ChromeOS: The accelerators are omitted since they caused major
> conflicts with the ChromeOS accelerator system. I spent a few days
> trying to fix this (Ex: updating tests, updating shortcuts, adding
> duplicate shortcuts similar to mac) but didn't find success.
