Rename UserDataKey to be unique (components/autofill)

When building using jumbo, files gets merged and
functions with the same name may end up in the same
namespace/scope and conflict. This happens for
the function UserDataKey. Since the function relies
on that the static int is unique this function could
not be moved to a shared util file. Instead, the issue
was solved by renaming the function.
