Add caches to TypeContextFactory method to prevent multiple parsing of the same classes by PHPStan property extractor.

1. Add cache to intermediate TypeContext creation from createFromClassName() and createFromReflection() by adding:

   • intermediateTypeContextCache proprety.
   • createIntermediateTypeContext() create the intermediate TypeContext if not found in cache.

2. Add cache to createFromClassName() by:

   • typeContextCache proprety.
   • extracting TypeContext creation to private createNewInstanceFromClassName() method.
   • refactoring createFromClassName() to get the TypeContext from $this->typeContextCache, or creating it by calling createNewInstanceFromClassName() method.

3. Add a test to check that the results are cached.

This optimize deserialization and form validation.
