RFR: 8323058: Revisit j.l.classfile.CodeBuilder API surface [v6]

[Adam Sotona]

> `java.lang.classfile.CodeBuilder` contains more than 230 API methods.
> Existing ClassFile API use cases proved the concept one big CodeBuilder is comfortable. However there are some redundancies, glitches in the naming conventions, some frequently used methods are hard to find and some methods have low practical use.
> 
> This patch revisits the `CodeBuilder` API methods and introduces some changes.
> 
> For more details, please, visit the [CSR ](https://bugs.openjdk.org/browse/JDK-8323067)
> 
> Please review.
> 
> Thank you,
> Adam
