Comprehensive WOW64 subsystem implementation (#555)

Browse Source 
# Major Features Implemented
**Core WOW64 Architecture**
1. Full TEB, PEB, and Windows structure implementations for 32-bit
processes
2. Proper thread context switching with 32-bit stack allocation
3. Configurable memory allocation with 32-bit/64-bit address space
handling
4. Automatic WOW64 process identification and handling
5. Heaven's Gate Implementation for handling exceptions

**Enhanced Emulation Features**
1. Fixed GDT setup and segment management for WOW64
2. Multi-architecture PE loading with proper import resolution
3. Segment-aware disassembly with WOW64 debugging capabilities

**Testing & Validation**
**32-bit Test Sample**: Minimal "hello" executable with full ASM source

# TODO
Needs more testing, currently in very early stages.
