WKPasswordView.mm is used on iOS-family devices. However, it doesn't build on tvOS or watchOS when "treat deprecation warnings as errors" is enabled. This build failure is due to a reference to UIColor.groupTableViewBackgroundColor in a branch of non-dark-mode code. Address this by surrounding the reference with ALLOW_DEPRECATED_DECLARATIONS_* macros.
Attempting to address the build failure by unconditionally enabling the dark-mode code works for tvOS, but fails for watchOS due to lack of dark-mode support on that platform.
