Fix two Auto-Type issues

[droidmonkey]

• Fix Windows Auto-Type sending characters to virtualized guests (Fix Autotype doesn't work if target window is VirtualBox instance #1833)
• Fix meta character usage in Auto-Type sequences (Fix Autotype special keys like ctrl or command are not working on macos #6695)

Note: Extended ASCII and Unicode characters cannot be sent to Virtual Machines. I tried many combinations of the windows virtual keyboard API and couldn't get it to work without breaking other major parts.

New meta modifier works on Linux 👍

Don't have a working Windows build env so can't say about the changes on that side.
