RFR: 8331608: Consolidate EncodeGCModeConcurrentFrameClosure and TransformStackChunkClosure [v3]

[Guoxiong Li]

> Hi all,
> 
> After [JDK-8296875](https://bugs.openjdk.org/browse/JDK-8296875), the classes `EncodeGCModeConcurrentFrameClosure` and `TransformStackChunkClosure` almost have the same code. This patch consolidates them into one.
> 
> The tests `make test-hotspot_loom` and `make test-hotspot_gc` passed locally (linux & x64). Thanks for taking the time to review.
> 
> Best Regards,
> -- Guoxiong
