renderer_vulkan: Add conditional rendering control setting

Browse Source 
Adds user option to disable Vulkan conditional rendering, which can fix
flickering objects in some games caused by rapidly toggled draw calls.

Changes:
- Add use_conditional_rendering setting (default: enabled)
- Guard conditional rendering functions with setting check using [[unlikely]]
- Early exit in Pause/Resume and Compare functions when disabled

Disabling this in Graphics (Advanced) fixes flickering at cost of performance.
