[VDG] Update to Avalonia 0.10.19

[wieslawsoltes]

Looks like Avalonia 0.10.19 has several bug fixes for windowing system, might be worth updating as v11 is still not ready.

AvaloniaUI/Avalonia@release/0.10.18...release/0.10.19

I think it fixes: #9193

Yes indeed.

I have not tested this intensively but over all LGTM.

There is no way to test this properly. Since we are just after release, we should just merge this and the problems will turn out soon on master if there are any.
