Unify and Streamline Il2Cpp Build Process for Clarity and Efficiency

This pull request incorporates two key improvements to the Il2Cpp build process:

1. Consolidated File Operations and Updated Folder Paths:

• Streamlined file management for Unity builds by:
  • Consolidating operations into a single directory (unityModulePath).
  • Updating folder paths for consistency.
  • Adding META-INF to targeted folders for manifest inclusion.
  • Implementing error handling to gracefully handle file issues.

2. Enhanced Il2Cpp Build Task with Refactoring and Extension Functions:

• Improved code organization and readability with refactoring.
• Introduced extension functions for:
  • Configuring ExecSpec for Il2Cpp execution.
  • Copying Il2Cpp symbol files.
  • Deleting unnecessary Il2Cpp files.
• Enhanced type safety and clarity in build task configuration.

Benefits:

• Simplified Code Structure: Easier understanding and maintenance.
• Improved Task Readability: Clearer intent and functionality.
• Enhanced Type Safety: Reduced potential for errors.
• Potential Performance Gains: Possible efficiency improvements.
• Robust Error Handling: Resilient to file-related issues.
