feat(windows): Get Keyman working together with AutoHotkey

**Is your feature request related to a problem? Please describe.**

Keyman and AutoHotkey don't work well together. This is particularly a problem if the serialised input queue is in use.

**Describe the solution you'd like**

Per https://community.software.sil.org/t/using-autohotkeys-with-keyman/3620/3:
> This then, is my request, to make Keyman work with AutoHotkey.

**Describe alternatives you've considered**

Turning serialised input off had other issues apparently: #4804.
