Feature/compute pipelines

[JohnSmoit]

Overview

Exposed vulkan's compute shader pipeline via the low-level Vulkan API and created a sample showing the most basic usage.

Changelog

• Implemented compute pipelines via a Compute wrapper type
• Expanded the Image type to support a wider variety of use cases such as "storage images"
• Expanded various command-based functions to allow direct injection into existing command buffers
• Created a basic sample application demonstrating a minimal working compute shader example
• Expanded the build system to accomodate building and running future samples easily
