[Generation] Create configuration path information parser

@bohdan-harniuk is already working on this.

Since Sep 7, 2022.

Create a configuration path info parser.
This task should be processed after the https://github.com/magento/magento2-phpstorm-plugin/issues/1163 is finished.
In that task will be specified expected output format for path information.

**Input:**

- a PsiFile object that referenced to the target system.xml file

**Output:**

Path information `List` of T that covered in the https://github.com/magento/magento2-phpstorm-plugin/issues/1163.

Info that should be included:

1. path to field (as for an ex.: b2b/general/enabled) -> **should be parsed**
2. scope info (showInDefault="1" showInWebsite="1" showInStore="1" -> **should be taken from the corresponding index** https://github.com/magento/magento2-phpstorm-plugin/issues/1165
3. field type (\Magento\Framework\Data\Form\Element\Factory::$_standardTypes) -> **should be taken from the corresponding index** https://github.com/magento/magento2-phpstorm-plugin/issues/1165
4. sort order

**Acceptance Criteria:**

- this generation should be covered by test case.
- all paths should be sorted by sort order in the system.xml file
