RFR: 8346984: Remove ASM-based benchmarks from Class-File API benchmarks

[Adam Sotona]

ASM-based benchmarks were useful to directly compare performance of ASM and Class-File API.
However Class-File API performance history is now continuously tracked and direct comparison to ASM becomes obsolete.

This patch removes ASM-based benchmarks from test/micro/org/openjdk/bench/jdk/classfile.

Please review.

Thanks,
Adam
