Include requires_extension from spec in AMP_Allowed_Tags_Generated

* Use spec to determine which script components get enqueued
* Use the latest component instead of 0.1
* Reduce duplicated logic by defining get_scripts() method on base sanitizer
* Add get_allowed_tag_data method on AMP_Allowed_Tags_Generated to reduce size of array passing.
* Define sanitized_tag class variable on sanitizer classes
