Windows: Implement mutex to serialize initialization across multiple VeraCrypt instances

When multiple VeraCrypt.exe instances were launched simultaneously, race conditions
could occur during the WM_INITDIALOG processing phase, potentially causing application
crashes or hang. This was because the initialization logic handles critical operations
like mounting/unmounting volumes and processing favorite volumes that modify global
system state.

This commit:
- Adds a named local session mutex (MainInitMutex) that serializes the WM_INITDIALOG handler
- Implements proper acquisition and release of the mutex during initialization
- Ensures proper cleanup of mutex resources on application exit
