Claude Bot b6e1db6acd Fix bindgen to properly inherit from ErrorInstance for Error.isError() support ...

Key changes to make ResolveMessage/BuildMessage proper ErrorInstance objects:

1. **Proper inheritance**: Classes with inheritsFromError:true now inherit from
   JSC::ErrorInstance instead of JSC::JSDestructibleObject

2. **Correct subspace allocation**: ErrorInstance classes use built-in error
   subspace instead of generating custom subspace methods

3. **Fixed constructor signatures**: ErrorInstance requires ErrorType::Error
   parameter in constructor

4. **Fixed finishCreation**: ErrorInstance requires message and cause parameters
   for proper initialization

5. **Set ErrorInstanceType**: JSType set to ErrorInstanceType for Error.isError()
   to return true

6. **Symbol property handling**: Fixed cached property generation to skip @@
   symbol properties that cause C++ syntax errors

This makes ResolveMessage objects proper Error instances that pass both
Error.isError() and instanceof Error checks.
