[Cleanup] Remove write-only CallLikeThisBoundClosureArgsNodeVisitor and its unread attribute

[TomasVotruba]

CallLikeThisBoundClosureArgsNodeVisitor sets the AST attribute IS_CLOSURE_USES_THIS ('has_this_closure') which is never read anywhere — not in src/, rules/, nor any sibling dev-main package (rector-downgrade-php, rector-symfony, rector-phpunit, ...). The only hasAttribute on the key sits inside the visitor's own guard; nothing consumes it.

It runs on every traversal via DECORATING_NODE_VISITOR_CLASSES yet produces nothing — pure overhead.

Removes:

• CallLikeThisBoundClosureArgsNodeVisitor
• CallLikeExpectsThisBoundClosureArgsAnalyzer (only that visitor used it)
• the unread AttributeKey::IS_CLOSURE_USES_THIS constant
• its registration + import in LazyContainerFactory

Pure deletion, 147 lines, no behavior change:

 private const array DECORATING_NODE_VISITOR_CLASSES = [
...
ClassConstFetchNodeVisitor::class,
- CallLikeThisBoundClosureArgsNodeVisitor::class,
ArgNotAcceptingClosureNodeVisitor::class,
];

Note: PhpVersionConditionNodeVisitor was in an earlier revision of this PR but is kept — its PHP_VERSION_CONDITIONED attribute is read cross-package by DowngradeHashAlgorithmXxHashRector in rector-downgrade-php.
