Disallow setting `innerHTML` inside the constructor

As @bennypowers points out in his tweet, https://twitter.com/PowersBenny/status/1383706876106395648

It can be detrimental to performance to set `innerHTML` inside the constructor. To accomplish this in a more performant way, you can create a static template and append that to the shadow dom instead.

This would be a fairly easy rule to detect and provide guidance for better perf.

Look at existing rules in the plugin to understand the AST patterns for detecting `innerHTML` assignments inside constructor methods. The rule should flag such usage and suggest using a static template. Check how other performance-related lint rules are structured and test with the project's test suite.
