[symfony] remove PreferAutowireAttributeOverConfigParamRule, too opinionated

[TomasVotruba]

Removes symfony.preferAutowireAttributeOverConfigParam rule.

The rule pushed #[Autowire(param: ...)] in-class attributes over param() references in config. This is very opinionated - config-based parameter injection is a valid, often preferable choice, so the rule does not always point to the better option.

Removed:

• rule + its identifier constant
• config registration in symfony-config-rules.neon
• tests + fixtures
• README section
• now-unused SymfonyClass::ATTRIBUTE and SymfonyFunctionName::PARAM constants
