b9d6efeb - [clang-tidy] Emit warning when user is using deprecated `zircon` checks (#189522)

[clang-tidy] Emit warning when user is using deprecated `zircon` checks (#189522) Add `utils::diagDeprecatedCheckAlias` so checks can detect whether they are running under a deprecated name without enabling the new names. This commit also comes with an example with `zircon` module. It is deprecated in 22 release but we didn't provide a note for it before.
