Add a flexible memory region management system that provides:
- Memory region type classification (System, Graphics, IO, Binary)
- Memory region permission management (executable, writable)
- Binary base address randomization for ASLR
- Dynamic memory mapping capabilities

Add more detailed debug logging and validation to the InvalidateNCE function:

- Add entry debug log showing NCE invalidation request details
- Add upfront validation of memory region before proceeding
- Add debug logs for rasterizer and separate heap handling cases
- Add warning logs for invalid address ranges and failed invalidations
- Improve error message formatting and clarity
- Group related operations with descriptive comments

These changes make it easier to debug NCE invalidation issues by providing
more visibility into the validation steps and failure cases.

- Update vcpkg baseline to a42af01b72c28a8e1d7b48107b33e4f286a55ef6
- Add SPIRV-Tools and SPIRV-Headers as submodules
- Update Vulkan-related submodules to latest stable versions
- Improve memory access error handling:
  - Add specific handling for null pointer accesses in ARM32 emulation
  - Return 0 for null pointer reads instead of undefined behavior
  - Silently ignore writes to null pointers
  - Add more detailed error messages distinguishing between null pointer
    access and other unmapped memory errors
  - Treat addresses below 0x1000 as potential null pointer accesses

These changes should provide more graceful handling of null pointer
accesses and improve stability when running games that attempt invalid
memory operations.

Allows the use of the macro in constexpr-contexts.
Also avoids some potential problems when nesting braces inside it.
