No internal styles rule proposal

[georgyangelov]

Proposal for a rule restricting breaking component encapsulation through style props

Description

First, this is a very crude WIP to see if you would accept such a rule. If you agree it's a good candidate I'll clean up the code and make it merge-ready. Please let me know what you think

Please see the docs/rules/no-internal-style.md file for an explanation of what the rule does.
