Merge branch 'master' into ractor-check-isolation

Master moved the Ractor isolation checks from "is this the main Ractor" to
class ownership (rb_class_owned_p) and turned RUBY_MN_THREADS into a mode
integer.  The conflicts are resolved by keeping master's conditions and
messages and routing them through rb_ractor_isolation_violation, so check
mode still downgrades them to warnings:

- variable.c, vm_insnhelper.c: ownership-based ivar/cvar/constant checks
  warn in check mode.  Class names are still formatted with rb_class_path,
  since a user to_s could re-enter the same check now that it can return.
- variable.c: rb_gvar_get/rb_gvar_set used to skip the lookup work and raise
  after releasing the VM lock.  In check mode the entry is still created and
  the access proceeds after the warning; otherwise it dereferenced NULL.
- class.c: rb_class_owner_check (def, include, define_method, ... on a class
  owned by another Ractor) goes through the same warn-or-raise path, so a
  check-mode sweep survives reopening a main-Ractor class.
- thread_sched.c: check mode raises RUBY_MN_THREADS to at least 1 and still
  clamps RUBY_MAX_CPU to 1; an explicit =2 is kept.
