Add autolabeler config

[LogvinovLeon]

Description

I've installed the autolabeler github app that automatically assignes github labels based on touched code. This PR configures it.
If you need to regenerate the list in future - I've used:

cd packages && grep -nr '"name": "' . | grep -v node_modules | grep -v lib | grep package.json | awk '{print $3}'

and a replacing regex: "@0x/(.*)" -> $1: ['packages/$1']
