cmake: Add Profile-Guided Optimization (PGO) support

Browse source 
Adds support for Profile-Guided Optimization builds on both Windows (MSVC)
and Linux (GCC/Clang) platforms. This allows for performance optimizations
based on real usage patterns.

For MSVC:
- Adds /GL and /LTCG:PGINSTRUMENT flags for instrumentation
- Adds /GL and /LTCG:PGOPTIMIZE flags for optimization

For GCC:
- Adds -fprofile-generate flags for instrumentation
- Adds -fprofile-use flags for optimization

For Clang:
- Adds -fprofile-instr-generate flags for instrumentation
- Adds -fprofile-instr-use flags for optimization

Controlled by two new CMake options:
- CITRON_ENABLE_PGO_INSTRUMENT: Enable instrumentation build
- CITRON_ENABLE_PGO_OPTIMIZE: Enable optimization build

Updated submodules:
- Vulkan-Headers to 0f0cfd8
- Vulkan-Utility-Libraries to 50563f4
- vcpkg to cd1099f
