Update Autoprefixer from 6.5.1 to 9.1.5

​https://github.com/postcss/autoprefixer/compare/6.5.1...9.1.5

Autoprefixer was upgraded in the 5.0 branch from 6.5.1 to 9.1.5 in [43684] as part of #45064.

As a follow up running grunt precommit updates numerous CSS files vendor prefixes and these changes require committing to the 5.0 branch.

The above changes should also be added to the /trunk branch for 5.1

The CSS changes from [43784] appear to be already merged to trunk in [43309] and [44264].

The only thing left to commit from 45080-trunk.diff​ is removing the /* Fails with spaces?? Weird! */ comment. It used to be next to -webkit-transform: translate( 50%, 50% ). [43784] moved it to height: 100% in the next line, which doesn't make sense.

Right, I believe the cause of this is that Autoprefixer cannot automatically remove vendor prefix lines if they have a comment at the end of the line.

As such the comment was moved, it should have been removed as it only applied to the vendor prefix line I believe.

I think this is all set now. @netweb can you verify and close this out?

Per the above, patch 45080.2.diff​ is required for /trunk
