Automatic code checks workflow

[MiranDMC]

Added new workflow doing checks of code file contents:

• verifies compliance with PSDK comment header template
• validates if comment states proper game name
• validates if comment states proper file type (header/source)
• validates if header files use #pragma once directive
• validates if there is VALIDATE_SIZE after each class or struct
• validates if there is VALIDATE_OFFSET for each member in class or struct

Fixed errors found by the workflow.
