  Log:
    `$SAFE` as a process global state. [Feature #14250]
    
    * vm_core.h (rb_vm_t): move `rb_execution_context_t::safe_level` to
      `rb_vm_t::safe_level_` because `$SAFE` is a process (VM) global state.
    
    * vm_core.h (rb_proc_t): remove `rb_proc_t::safe_level` because `Proc`
      objects don't need to keep `$SAFE` at the creation.
      Also make `is_from_method` and `is_lambda` as 1 bit fields.
    
    * cont.c (cont_restore_thread): no need to keep `$SAFE` for Continuation.
    
    * eval.c (ruby_cleanup): use `rb_set_safe_level_force()` instead of access
      `vm->safe_level_` directly.
    
    * eval_jump.c: End procs `END{}` doesn't keep `$SAFE`.
    
    * proc.c (proc_dup): removed and introduce `rb_proc_dup` in vm.c.
    
    * safe.c (rb_set_safe_level): don't check `$SAFE` 1 -> 0 changes.
    
    * safe.c (safe_setter): use `rb_set_safe_level()`.
    
    * thread.c (rb_thread_safe_level): `Thread#safe_level` returns `$SAFE`.
      It should be obsolete.
    
    * transcode.c (load_transcoder_entry): `rb_safe_level()` only returns
      0 or 1 so that this check is not needed.
    
    * vm.c (vm_proc_create_from_captured): don't need to keep `$SAFE` for Proc.
    
    * vm.c (rb_proc_create): renamed to `proc_create`.
    
    * vm.c (rb_proc_dup): moved from proc.c.
    
    * vm.c (vm_invoke_proc): do not need to set and restore `$SAFE`
      for `Proc#call`.
    
    * vm_eval.c (rb_eval_cmd): rename a local variable to represent clearer
      meaning.
    
    * lib/drb/drb.rb: restore `$SAFE`.
    
    * lib/erb.rb: restore `$SAFE`, too.
    
    * test/lib/leakchecker.rb: check `$SAFE == 0` at the end of tests.
    
    * test/rubygems/test_gem.rb: do not set `$SAFE = 1`.
    
    * bootstraptest/test_proc.rb: catch up this change.
    
    * spec/ruby/optional/capi/string_spec.rb: ditto.
    
    * test/bigdecimal/test_bigdecimal.rb: ditto.
    
    * test/fiddle/test_func.rb: ditto.
