RFR: 8331291: java.lang.classfile.Attributes class performs a lot of static initializations [v9]

[Adam Sotona]

> Hi,
> During performance optimization work on Class-File API as JDK lambda generator we found some static initialization killers.
> One of them is `java.lang.classfile.Attributes` with tens of static fields initialized with individual attribute mappers, and common set of all mappers, and static map from attribute names to the mappers.
> 
> I propose to turn all the static fields into lazy-initialized static methods and remove `PREDEFINED_ATTRIBUTES` and `standardAttribute(Utf8Entry name)` static mapping method from the `Attributes` API class.
>  
> Please let me know your comments or objections and please review the [PR](https://github.com/openjdk/jdk/pull/19006) and [CSR](https://bugs.openjdk.org/browse/JDK-8331414), so we can make it into 23.
> 
> Thank you,
> Adam
