renderer_vulkan: Rewrite descriptor set management and various small fixes (#77)

Browse Source 
* renderer_vulkan: Remove vulkan prefix in SetObjectName

* renderer_vulkan: Rename renderpass cache to render manager

* It is no longer just a cache

* renderer_vulkan: Rewrite descriptor management

* Switch to batched vkUpdateDescriptorSets from cached descriptor sets with templates

* vk_master_semaphore: Remove waitable atomic

* These are buggy on some platforms and regular condition_variables are faster most of the time

* vk_texture_runtime.cpp: remove outdated references

* vk_render_manager: Minor cleanups and rename to RenderManager

* It is no longer just a renderpass cache
* Revert variable name change from render_manager back to renderpass_cache
