RFR: 8364929: Assign unique id to each AdapterBlob stored in AOTCodeCache [v5]

[Ashutosh Mehra]

> This patch assigns unique id to each AdapterHandlerEntry so as to avoid using hash computed from AdapterFingerPrint which may not be unique. Unique id allows AOTCodeCache to locate the AdapterBlob being requested to be loaded.
> 
> Testing:
> Before this patch `runtime/cds/appcds/aotClassLinking/StringConcatStress.java` emits warning messages in the production run:
> 
> [0.009s][warning][aot,codecache,stubs] Saved blob's name 'LIIDIIIDL' is different from the expected name 'LIIDIIDL'
> [0.009s][warning][aot                ] Failed to link AdapterHandlerEntry (fp=LIIDIIDL) to its code in the AOT code cache
> [0.009s][warning][aot,codecache,stubs] Saved blob's name 'IILLLLIIIIII' is different from the expected name 'IILLLLLILIII'
> [0.009s][warning][aot                ] Failed to link AdapterHandlerEntry (fp=IILLLLLILIII) to its code in the AOT code cache
> 
> With this patch, such warnings are not seen at all
