Bug #21159: `Module#set_temporary_name` should freeze given name

----------------------------------------
I think it is preferable to freeze the name.
So `#set_temporary_name` should copy and freeze the name string.
```ruby
c = Class.new.set_temporary_name(str = +'<c>')
p c #=> <c>
str.upcase!
p c #=> actual: <C>
#=> expected: <c>
p c.name.frozen?
#=> actual: false
#=> expected: true
```
>>From the Ractor's aspect, shareable modules should refer only immutable string.
