Subject: [PATCH] fix(zone.js): Add 'declare' to each interface to prevent
 renaming (#54966)

This commit adds `declare` to each interface in the `zone-impl` to
prevent renaming of any interface properties by compiler optimizations.
This would otherwise cause issues if multiple applications depend on ZoneJS and
compile the interface properties to different names.

PR Close #54966
