Postcss support

[lancetharper]

Would love to get support for postcss. I've forked to explore this and am hopeful to submit a PR for it

[jeremyzahner]

@lancetharper Maybe look at the SASS/SCSS implementation since it should be the most complete one.

[lancetharper]

@jeremyzahner I looked at the SASS examples and they are using renderSync. It looks like postcss needs to be async to support async plugins though. Is this even possible without rewriting all of vue-jest to be async?

[eddyerburgh]

vue-jest can't be async, because jest transforms can't be async.

What plugins need to be async?

[lancetharper]

I'm not sure which ones are, I just get a warning saying async plugins won't work if postcss isn't run async.

I don't know if there is a sync method for automatically loading the configs either.
