Add a setting to flash the taskbar when the terminal emits BEL (#8215)
The terminal taskbar icon can now flash when the BEL sequence is
emitted, to let the user know something needs their attention. 

The `BellStyle` setting can now be set to `audible`, `visual` or both or
none. When the pane receives a BEL event and the `bellStyle` includes
`visual`, we bubble the event up all the way to `AppHost` to handle
flashing the taskbar. 

Closes #1608
