PHP 8.4 Support: Asymmetric Visibility v2 (Part 1)

- apache#8035
- https://wiki.php.net/rfc#php_84
- https://wiki.php.net/rfc/asymmetric-visibility-v2
- https://www.php.net/manual/en/language.oop5.final.php

- Fix the lexers and the parser(grammar file)
- Support for the `final` field(property)
- Don't handle modifier errors for methods, constants, and fields in the parser. Instead, handle them in the hint error.
  Writing all valid cases for each member is very hard and complicated because the current PHP has many modifiers.
- Fix the `PHP84UnhandledError`
- Add/Fix unit tests for the navigator, lexer, and parser

Example:
```php
class AsymmetricVisibilityClass {
    // Constructor Property Promotion
    public function __construct(
        public(set) string $field1, // implicit public
        public private(set) int $field2,
        public protected(set) readonly int $field3,
    ) {}

    // valid fields
    public(set) string $example1; // implicit public
    pulbic private(set) int $example2 = 1;
    public protected(set) readonly int $example3;
    final private private(set) readonly string|int $example4; // final is available as of PHP 8.4

    // invalid cases but the parser doesn't handle them as errors
    // e.g.
    public public string $invalid1 = "invalid"; // multiple same modifiers
    final private private(set) string|int $invalid2; // cannot use both final and private
    public public(set) $invalid3; // need type
    private public(set) string $invalid4; // visibility(private) must not be weaker than set visibility
}
```
