Implement Framebuffer Cache

Browse Source 
Implements a cache for storing `VkFramebuffer` objects with a special path on devices with `VK_KHR_imageless_framebuffer` to allow for more cache hits due to an abstract image rather than a specific one. 

Caching framebuffers is a fairly crucial optimization due to the cost of creating framebuffers on TBDRs since it involves calculating tiling memory allocations and in the case of Adreno's proprietary driver involves several kernel calls for mapping and allocating the corresponding framebuffer memory.
