build: update dependencies and relax version requirements

- Update Vulkan validation layers to 1.4.304.1
- Update Qt to 6.8.2
- Remove strict version requirements for various dependencies
- Update Vulkan-Headers, VulkanMemoryAllocator, and vcpkg submodules
- Reorganize discord-rpc compile options

This change makes the build system more flexible by removing unnecessary
version constraints while ensuring compatibility with newer versions of
key dependencies.
