separate some fields from rb_ractor_t to rb_ractor_pub and put it
at the beggining of rb_ractor_t and declare it in vm_core.h so
vm_core.h can access rb_ractor_pub fields.

Now rb_ec_ractor_hooks() is a complete inline function and no
MJIT related issue.

separate synchronization data and ractor local data.

Write barrier requires VM lock because it accesses VM global bitmap
but RB_VM_LOCK_ENTER() can invoke GC because another ractor can wait
to invoke GC and RB_VM_LOCK_ENTER() is barrier point. This means that
before protecting by a write barrier, GC can invoke.
To prevent such situation, RB_VM_LOCK_ENTER_NO_BARRIER() is introduced.
This lock primitive does not become GC barrier points.

Before this patch, there is no information to start locking.

This is variant of RB_VM_LOCK_ENTER_LEV, but accept current racotr's
pointer.
