hw/cxl/cxl-mailbox-utils: Add mailbox commands to support add/release dynamic capacity response
Per CXL spec 3.1, two mailbox commands are implemented:
Add Dynamic Capacity Response (Opcode 4802h) 8.2.9.9.9.3, and
Release Dynamic Capacity (Opcode 4803h) 8.2.9.9.9.4.
For the process of the above two commands, we use two-pass approach.
Pass 1: Check whether the input payload is valid or not; if not, skip
Pass 2 and return mailbox process error.
Pass 2: Do the real work--add or release extents, respectively.
