RFR: 8326096: Deprecate getTotalIn, getTotalOut methods of java.util.zip.Inflater, java.util.zip.Deflater [v12]

[Eirik Bjørsnøs]

> Please review this PR which proposes that we officially deprecate the following four methods in the `java.util.zip` package:
> 
> * `Inflater.getTotalIn()`
> * `Inflater.getTotalOut()`
> * `Deflater.getTotalIn()`
> * `Deflater.getTotalOut()`
> 
> Since these legacy methods return `int`, they cannot safely return the number of bytes processed without the risk of losing information  about the magnitude or even sign of the returned value.
> 
> The corresponding methods `getBytesRead()` and `getBytesWritten()` methods introduced in Java 5 return `long`, and should be used instead when obtaining this information. 
> 
> Unrelated to the deprecation itself, the documentation currently does not specify what these methods are expected to return when the number of processed bytes is greater than `Integer.MAX_VALUE`. This PR aims to clarify this in the API specification.
