Keep the global proxy's DontDelete attribute when the sandbox also contains the property, so lexical redeclarations are rejected. Signed-off-by: subotac <73706465+subotac@users.noreply.github.com>

Global function declarations in a context can be reflected as configurable sandbox properties while V8 tracks their global bindings as non-configurable.
When the property query interceptor finds the sandbox property first, preserve the
DontDeleteattribute from the global proxy. This ensures that a subsequent lexical declaration is rejected with aSyntaxError.Extend the existing restricted-global-property test to cover a function declaration followed by a conflicting lexical declaration.
