Support "Search" as a modifier specified in a chrome.commands manifest.
BUG=404766
TEST=Using a sample extension,
"commands": {
"foo": {
"suggested_key": {
"chromeos": "Search+Shift+L"
...
and adding a listener to onCommand, pressing Search+Shift+L results in triggering of the callback. (on linux, this is lwindows+shift+l).
