Introduce CommandExecutor + Implement ClearBuffers + More RT Formats

This commit introduces the `CommandExecutor` which is responsible for creating and orchestrating a Vulkan command graph comprising of `CommandNode`s that construct all the objects required for rendering. As a result of the infrastructure provided by `CommandExecutor`, `ClearBuffers` could be implemented and be appropriately utilized.

A bug regarding scissors was also determined and fixed in the PR, the extent of them were previously inaccurate and this has now been fixed.

Note: We don't synchronize any textures from the guest for now as this would override the contents on the host, this'll be fixed with the appropriate write tracking but it also results in a black screen for anything that writes to FB
