Disable retry capture at lower resolution

A mechanism was introduced to retry capture at a lower resolution to
support devices unable to encode at the device screen resolution.

While useful, this approach is inherently limited and will not be able
to handle the dynamic resizing required for resizable virtual displays.

Disable this mechanism entirely. Further commits will add support for
adjusting the size in advance according to video encoder capabilities.
