autoprefixer, browserslist: update, move to package.json

we're using old autoprefixer which depends on browserslist 1.7, which doesn't know "not dead" - updating autoprefixer, and stylelint because that depends on an older version too

then moving our browserslist from babel config to global config,
so that autoprefixer picks it up automatically,
and doesn't generate IE CSS.

Prevents errors when requiring carbon:

    (9155:3) IE supports only grid-row with / and span. You should add grid: false option to Autoprefixer and use some JS grid polyfill for full spec support
