fix(ivy): resolve enum values in host bindings (#28523)

Some applications use enum values in their host bindings:

@Component({
  host: {
    '[prop]': EnumType.Key,
  }, ...
})

This commit changes the resolution of host properties to follow the enum
declaration and extract the correct value for the binding.
