Bug #19409: Object's shape is reset after a ractor move
https://bugs.ruby-lang.org/issues/19409
* Author: luke-gru (Luke Gruber)

* Priority: Normal

----------------------------------------
I believe an object should have the same shape after being moved from 1 ractor to
another.
```ruby
class Obj
attr_accessor :a, :b, :c, :d
def initialize
@a = 1
@b = 2
@c = 3
end
end
r = Ractor.new do
obj = receive
#p RubyVM::Shape.of(obj)
obj.d = 4
p obj.a, obj.b, obj.c, obj.d # gets wrong values due to object shape id being reset on
object
end
obj = Obj.new
#p RubyVM::Shape.of(obj)
r.send(obj, move: true)
r.take
```
