Add new rule for detecting legacy HTML filtering rule syntax

Deprecate old HTML filtering syntax, and suggest the modern approach. For example

- `tag-content` should be replaced by `contains`:
```adblock
example.com$$script[tag-content="foo"]
```
↓↓↓ should be fixed as ↓↓↓
```adblock
example.com$$script:contains(foo)
```
- `wildcard` should be replaced by `contains`, and glob pattern should be replaced by regular expression:
```adblock
example.com$$script[wildcard="*banner*text*"]
```
↓↓↓ should be fixed as ↓↓↓
```adblock
example.com$$script:contains(/banner.*text/)
```

Suggested rule name: `no-legacy-html-filtering-syntax`
