[browser] JSExport missing global::

[pavelsavara]

Fixes #116254

[Copilot]

Pull Request Overview

This PR ensures that generated JS export stubs and tests use the global:: alias to avoid ambiguities when calling methods on the Basic class.

• Unit tests now explicitly invoke Basic.AnnotatedExport and Basic.Export1 with global:: qualification.
• The JS export generator prefixes method invocations with the global alias in the generated stub.

• Using IdentifierName to represent a global alias–qualified name will produce invalid syntax. Consider using ParseName(TypeNames.GlobalAlias + context.SignatureContext.MethodName) or constructing an AliasQualifiedNameSyntax to correctly model global::Basic.MethodName.

It seems CI failures are infra issue. The relevant test passed.
