Add ParenthesizeNegatedInstanceofRector

[jeromegamez]

Adds (or removes) parentheses around negated instanceof expressions:

# rector.php
use Rector\Instanceof_\Rector\BooleanNot\ParenthesizeNegatedInstanceofRector;

RectorConfig::configure()
    ->withRules([
        ParenthesizeNegatedInstanceofRector::class // defaults to `add_parentheses`
    ])
	// or
    ->withConfiguredRule(ParenthesizeNegatedInstanceofRector::class, [)
        'mode' => ParenthesizeNegatedInstanceofRector::ADD_PARENTHESES, // `add_parentheses`
    ])
	// or
    ->withConfiguredRule(ParenthesizeNegatedInstanceofRector::class, [)
        'mode' => ParenthesizeNegatedInstanceofRector::REMOVE_PARENTHESES, // `remove_parentheses`
    ])
;

this will either

# With `add_parentheses`
-!$foo instanceof Foo
+!($foo instanceof Foo)

# With `remove_parentheses`
-!($foo instanceof Foo)
+!$foo instanceof Foo

Hi, thanks for proposal. Rector area of focus is logic code structures.
As this rule brings syntactical improvement, it fits tools like php-cs-fixer. Contribute this rule there 👍

Thank you for looking into this, I hope I can use parts of it, this was a long debugging session (I first thought setting the attribute to false would be enough) 😅
