    CL/Vulkan: Allocate descriptor sets under lock
    
    Multiple threads in the application are accessing the OpenCL
    runtime simultaneously, resulting in multiple SharedPtr of
    mDynamicDescriptorPools[] being created for a single context.
    
    This can lead to incorrect reference counting and
    potentially cause `DynamicDescriptorPool::destroy` to be
    called unexpectedly. This fixes the concurrent access issue
    through acquiring the descriptor set mutex
    just before initializing mDynamicDescriptorPools to ensure that
    only one mDynamicDescriptorPools[] is created per context.
