Implement ConEmu's OSC 9;4 to set the taskbar progress indicator (#8055)
This commit implements the OSC 9;4 sequence per the [ConEmu style].

| sequence                   | description                                       |
| ------------               | ------------                                      |
| `ESC ] 9 ; 4 ; st ; pr ST` | Set progress state on taskbar and tab.            |
|                            | When `st` is:                                     |
|                            |                                                   |
|                            | `0`: remove progress.                             |
|                            | `1`: set progress value to `pr` (number, 0-100).  |
|                            | `2`: set the taskbar to the "Error" state         |
|                            | `3`: set the taskbar to the "Indeterminate" state |
|                            | `4`: set the taskbar to the "Warning" state       |

We've also extended this with:
* st 3: set indeterminate state
* st 4: set paused state

We handle multiple tabs sending the sequence by using the the last focused
control's taskbar state/progress.

Upon receiving the sequence in `TerminalApi`, we send an event that gets caught
by `TerminalPage`. `TerminalPage` then fires another event that gets caught by
`AppHost` and that's where we set the taskbar progress. 

Closes #3004
