[Generation] Create configuration path information indexer

[bohdan-harniuk]

Corresponding indexer should be created or existent extended to hold next information stored by path to field as an identity:

1. scope info (showInDefault="1" showInWebsite="1" showInStore="1")
2. field type (\Magento\Framework\Data\Form\Element\Factory::$_standardTypes)
3. sort order

Output:

After indexation we should be able to get expected info for any existing path in the project.
