Context-Based API Factory methods

[JohnSmoit]

Overview

Make all vulkan object creation a factory based on an application context so that I can integrate additional logic to be executed for all handle initializations. This would integrate well with the resource manager in addition to allowing for easier decoupling of logic and state for created objects.

Updates:

• For now I'm going to focus on the bare essentials of this system, so only pooled memory will be supported, which is fine since that's the default anyways.
• A general-purpose destroy resource function should also be provided by factories.
• API function should be included in the proxy type, preferably without a bunch of useless wrapper functions for converting handles to pointers.
