feat: implement using/await using declarations with SuppressedError

[xcb3d]

It changes the following:

• Implement using and await using declaration parsing with proper guards for line terminators (using\nlet triggers ASI), bracket tokens (using[0] is element access), and for (using of of arr) disambiguation
• Add SuppressedError built-in constructor (core/engine/src/builtins/error/suppressed.rs) with full prototype chain inheriting from Error, registered as a global binding
• Add disposal VM opcodes (CreateDisposeCapability, AddDisposableResource, DisposeResources) implementing the spec's DisposeResources abstract operation with proper error chaining via SuppressedError
• Fix DisposeResources to incorporate pending exception as the initial completion per spec, so body errors and disposal errors are properly combined in the SuppressedError chain
• Add IterableLoopInitializer::Using variant for for-of loops with immutable binding semantics
• Block using declarations in switch clause bodies and top-level scripts per spec early errors
