General: Separate extraction of template data into more functions

[iLLiCiTiT]

Brief description

Separated get_workdir_data into smaller functions and moved them into openpype.pipeline.

Description

Created new file ./openpype/pipeline/template_data.py which contains functions related to template data preparation. Function get_workdir_data was split into get_general_template_data, get_project_template_data, get_asset_template_data and get_task_template_data. All of them are covered with universal get_template_data or get_template_data_with_names which are calling the teparated functions based on passed arguments.

Functions get_workdir_data and get_system_general_anatomy_data were marked as deprecated and their usages were replaced with new functions.

Additional information

Added Deprecated category into docstrings of deprecated functions telling when will be removed.

Testing notes:

• Application should be launched and should be able to use last workfile as before
• TVPaint load workfile
• Nuke create write node should use right template for output path (and fill it to write node)
• Unreal prelaunch hook for workfile should work as did
• Ftrack action to fill workfile attribute should work as before
• Collect anatomy template data should be filled correctly
• Workfiles tool - Save As dialog should work
