Pull request overview

Adds a new semantic diagnostic to report an error when await using is used inside a class static initialization block, and updates the TypeScript parser coverage snapshot accordingly.

Changes:

• Introduce a new OxcDiagnostic constructor for await using in class static blocks.
• Add a semantic check in the JS/TS semantic checker to emit that diagnostic for VariableDeclarationKind::AwaitUsing within class static blocks.
• Update the TypeScript coverage snapshot to reflect the newly reported error and the updated negative-pass count.
