immutable Pair, better performant HttpBearerAuth, consistent code-style (#20743)

* make Pair immutable and in google-code-style

* apply google-code-style to JavaTimeFormatter (to make it consistent with most other auto-generated java)

* move upperCaseBearer to ctor (scheme is final and private; only needs to be fixed once); also replaced Optional with ternary (perf and cleaner code)

* apply google-code-style to Authentication to make it consistent with rest of auth code

* fresh samples
