- Adds testing for Vulkan pipeline caching.
- Removed redundant VK_NULL_HANDLE and use explicit {} initialization for 0 handles when necessary.
- Adds some const qualifiers where applicable and useful.
- Removes overloaded GetCacheKey (const/non-const) versions and exposed the cache key member directly for modifiers in derived classes.
