Add initial project structure and audio shims for LCE Xbox port

Browse Source 
- Added Wide310x150Logo.png asset for application branding.
- Created LCE.Xbox project file with configurations for Debug and Release.
- Added Package.appxmanifest for application metadata and capabilities.
- Introduced SharedSurface.h for shared memory management between processes.
- Implemented AudioShim with XAudio2 integration for audio playback.
- Developed XSBParser and XWBParser for handling sound bank files.
- Created DXGIShim to intercept DXGI calls and manage swap chains.
- Defined project files for AudioShim and DXGIShim with necessary dependencies.
