8340181: Shenandoah: Cleanup ShenandoahRuntime stubs

[shipilev]

Noticed this while working on Leyden, which has to enumerate Shenandoah stubs for code archival to work.

ShenandoahRuntime::shenandoah_clone_barrier is excessive name. ShenandoahRuntime::arraycopy_barrier_oop_entry and friends is not covered by JRT_LEAF. This change hopefully homogenizes the namings for the stubs.

Additional testing:

• Linux x86_64 server fastdebug, hotspot_gc_shenandoah
• Linux AArch64 server fastdebug, hotspot_gc_shenandoah
