RFR: 8306855: [s390x] fix difference in abi sizes [v2]

[Amit Kumar]

> This PR equals the interpreter, native abi sizes. JIT abi is completely removed as it was not being used anywhere in s390x code base. Apart form it, `z_abi_16` was replaced by `z_common_abi` and some other renaming followed this ladder.
> 
> Builds `slowdebug, fastdebug, release, optimized` are okay. `tier1-tests on fastdebug-build` are not affected as well.
