MSAA with 8 samples crashes when using vulkan on windows 10

## Bevy version

0.6

## Operating system & version

Edition Windows 10 Pro
Version 21H2
Installed on ‎2/‎27/‎2021
OS build 19044.1526
Experience Windows Feature Experience Pack 120.2212.4170.0

## What you did

```
let mut app = App::new();
app.insert_resource(Msaa { samples: 8 })
.insert_resource(engine)
.insert_resource(action_sender)
.insert_resource(contract)
.add_plugins(DefaultPlugins)
.add_plugin(ShapePlugin)
.add_startup_system(setup) // initial game logic
.add_system(update_position); // game logic
```

## What you expected to happen

the program runs

## What actually happened

It crashed. I'm sorry I don't have more info! I can't really share my code, but I'm not doing anything fancy with bevy. It looks like it is using vulkan on windows though, when I would have expected it to use directx. I figured I would share the crash log at least in case it is relevant.

**Setting samples to 4 solves the problem.** Why? I'm not sure. I'm also still not sure why its using vulkan. Is that the default?

## Additional information
