Mario Kart 8 Deluxe and Deltarune got tested by Isaac with help from
Peri previosly (His video: https://www.youtube.com/watch?v=GEVre_0ZVUg
)

Captain Toad, Cuphead and Animal Crossing I tested myself (side-by-side
Video comparison: https://youtu.be/auNS9MmZMPI )

Additional information:

Cuphead has flickering issues with certain UI elements on Vulkan via
MoltenVK. Metal fixes those and introduces no new issues, according to
my testing.

Animal Crossing is accurate, except for it having broken backgrounds in
interiors, causing them to appear as white instead of black. This is
caused by a hardware level sampler bug, that isaac never got to find a
workaround for.
However, this issue happens with Vulkan via MoltenVK as well, both Metal
and Vulkan have this issue, therefore Metal shouldn't have any downside
compared to using Vulkan in this game.

Optimize locale loading (remove always loading english, that was only needed with the old system)

add bulk property change event method
give each markup extension its own property name

Add more NotificationHelper methods
Simplify ID copy logic

This is not a continuation of the Metal backend; this is simply bringing
the branch up to date and merging it as-is behind an experiment.

Custom refresh rate locales and fixed a couple others too

Minor but useful quality of life addition

UI: Move Match PC Time to next to the time selector & change label & tooltip to clarify behavior further.

Partially resolves #355. I think that wanted automatic. If automatic functionality is still desired even with this change then that will be considered.

UI: Change "System Version" to "Firmware Version" and change 0.0 when firmware is not installed to NaN
