Replace deprecated `stateChanged` function with `checkStateChanged` that was first introduced in QT 6.7 but keep the old code to maintain compatibility with older versions of QT.
* 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* vk_texture_runtime.cpp: remove outdated references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
