    dmadev: add inter-domain control plane API
    
    Secure and controlled inter-domain DMA transfers require dedicated
    control-plane APIs to create and manage access groups.
    
    DMA devices used for inter-process data transfer can be categorized as
    follows:
    
    Class A: Both endpoints require a DMA device for data transfer (e.g.,
    Marvell DMA devices).
    Class B: Only one endpoint requires a DMA device; the other does not.
    Class C: Other device types not currently classified.
    
    Providing a unified API for all these categories is complex, as Linux
    and other operating systems do not offer native control-plane APIs for
    this purpose. Therefore, DPDK can implement its own control-plane
    mechanisms to support Class A, B, and C devices.
    
    This commit introduces the necessary APIs for Class A DMA devices.
    Devices can create or join access groups using token-based
    authentication, ensuring that only authorized devices within the same
    group can perform DMA transfers across processes or OS domains.
    
    API Usage Flow:
    
    Process 1 (Group Creator):
    Invokes rte_dma_access_pair_group_create() to establish a new access
    pair group, then shares the group_id and token with Process 2 via IPC.
    
    Process 2 (Group Joiner):
    Receives the group_id and token from Process 1 and calls
    rte_dma_access_pair_group_join() to join the group.
    
    Both Processes:
    Use rte_dma_access_pair_group_handler_get() to obtain handler information
    for domains in the group.
    Perform DMA transfers as required.
    
    Process 2 (when finished):
    Calls rte_dma_access_pair_group_leave() to exit the group.
    
    Process 1:
    Monitors for group updates and confirms group membership as needed.
