This is ineffective. This method was already called once inside findTypeAndMethodNames above. It's a bit of a mess right now.
I just made sure this kind of mistake isn't possible: 30b9cd8
So the fix should probably be done inside findTypeAndMethodNames but I'm not sure.

Not sure too. Depends of the purpose of the method.
Currently the findTypeAndMethodNames returns all the possible callable with at least a Maybe certainty. Cf #3637 (comment)
Currently it's not possible to create
ConstantArrayTypeAndMethod::createConcrete($type, $method->getValue(), TrinaryLogic::createNo());
So if you have a string 'foo'|'bar' and only 'foo' is a callable name, if it will returns 'foo'.
But it doesn't mean that 'foo'|'bar' is always a callable.
That's why I added the logic in isCallable to check the count of possible callable didn't drop (which mean some value has No as certainty).
Reopened from #3637 since I messed up with my branches (and the previous changes was on 1.12.x branch...)
Closes phpstan/phpstan#12063
