core/hle: Implement TMA (Target Manager Agent) service

Add implementation for the TMA service which provides file I/O
and debugging functionality for development tools.

Changes:
- Add TMA service with IFileManager, IFileAccessor, and IDirectoryAccessor
- Implement stubbed file operations (ReadFile, WriteFile, GetFileSize, etc.)
- Implement stubbed directory operations (ReadDirectory, GetEntryCount, etc.)
- Add TMA logging category for service debugging
- Fix parameter alignment in ReadFile function signature

All functions are provided as-is to allow games and development tools to initialize
without errors.
