Bug 1780318: Handle keyboard activation in Windows SystemStatusBar. r=mconley

Browse Source 
When the user wishes to open the window with the mouse, the shell sends NIN_SELECT.
We could continue to use WM_LBUTTONUP there, but the semantic notification is probably better.
When the user presses the space/enter key to open the window, the shell sends NIN_KEYSELECT.
When the user activates the context menu either with the mouse or the keyboard (applications/shift+f10 key), the shell sends WM_CONTEXTMENU.
