/**
 * The DynamicBuffers class provides a dynamic memory allocation system for uniform buffer data,
 * particularly for non-persistent uniform buffers. This class utilizes a bump allocator to
 * efficiently allocate aligned memory space from a set of large buffers managed internally. To
 * utilize this system, the user writes data to CPU-accessible staging buffers. When submitting
 * command buffers that require these buffers, the system automatically uploads the data to the GPU
 * buffers. This approach ensures efficient memory management and smooth data transfer between the
 * CPU and GPU.
