hw/cxl/mbox: Generalize the CCI command processing
By moving the parts of the mailbox command handling that are CCI type specific out to the caller, make the main handling code generic. Rename it to cxl_process_cci_message() to reflect this new generality. Change the type3 mailbox handling (reused shortly for the switch mailbox CCI) to take a snapshot of the mailbox input data rather than operating on it in place. This reduces the chance of bugs due to aliasing going forwars.
