Use the Continuous update mode in stress tests when unfocused (#11652)

# Objective

- When running any of the stress tests, the refresh rate is currently
capped to 60hz because of the `ReactiveLowPower` default used when the
window is not in focus. Since stress tests should run as fast as
possible (and as such vsync is disabled for all of them), it makes sense
to always run them in `Continuous` mode. This is especially useful to
avoid capturing non-representative frame times when recording a Tracy
frame.

## Solution

- Always use the `Continuous` update mode in stress tests.
