Optimize `ParseMessageWithLength()` and indirectly
`ParseLengthPrefixedMessage()` when `src` is statically known to be a
`LimitingReaderBase`.

In this case `ScopedLimiter` on `src` is used instead of creating a new
`LimitingReader`.

Add `ScopedLimiterOrLimitingReader` to capture this pattern.

This benefits `SerializedMessage{Reader,Rewriter}::OnParsedMessage()`.
