refactor(i18n): use common messages for generic button labels (#7020)

A few components defined their own "Cancel", "Close", "Clear" and
"Success" descriptors when commonMessages already has them. Swapped
them over and removed the old ones.

Locale files come from intl:prune-local dropping the now-orphaned
strings across every language.
