fix `defined?(@ivar)` with Ractors
`defined?(@ivar)` on the non main Ractor has two issues:
1. raising an exception
```ruby
class C
@iv1 = []
def self.defined_iv1 = defined?(@iv1)
end
Ractor.new{
p C.defined_iv1
#=> can not get unshareable values from instance variables of classes/modules from non-main Ractors (Ractor::IsolationError)
}.take
```
-> Do not raise an exception but return `"instance-variable"` because
it is defined.
2. returning `"instance-variable"` if there is not defined.
```
class C
# @iv2 is not defined
def self.defined_iv2 = defined?(@iv2)
end
Ractor.new{
p C.defined_iv2 #=> "instance-variable"
}.take
```
-> returns `nil`
