feat(material/theming): Disambiguate token names in theme overrides (#29859)

Prior to this change a single key in the theme overrides map sometimes
resulted in mutliple tokens being overridden. This change gives every
token a unique name, by prefixing when necessary. The old ambiguous keys
are still allowed for compatibility, but will now log a warning when
they're used.
