hw/pci-bridge/cxl_upstream: Move defintion of device to header. To avoid repetition of switch upstream port specific data in the CXLDeviceState structure it will be necessary to access the switch USP specific data from mailbox callbacks. Hence move it to cxl_device.h so it is no longer an opaque structure.

hw/cxl: Add a switch mailbox CCI function CXL switch CCIs were added in CXL r3.0. They are a PCI function, identified by class code that provides a CXL mailbox (identical to that previously defined for CXL type 3 memory devices) over which various FM-API commands may be used. Whilst the intent of this feature is enable switch control from a BMC attached to a switch upstream port, it is also useful to allow emulation of this feature on the upstream port connected to a host using the CXL devices as this greatly simplifies testing.
