The MACRO of IVSHMEM shared region name is relevant to scenario, move
the MACRO from pci_devices.h which should be consistent for different
scenarios to ivshmem_cfg.h which is the configuration for IVSHMEM and
could vary in sceanrios.

This patch is to support the Inter-VM communication by IVSHMEM
in config tool.
Users can configure IVSHMEM_ENABLE to enable or disable Inter-VM
communication by IVSHMEM; users can configure the name, size,
communication VM IDs of the IVSHMEM devices in the VM settings of
scenario xmls, then config tool will generate the related IVSHMEM
configurations for Inter-VM communication.
The config tool will do sanity check including when saving the xmls:
the format of shared memory region configuration is
[name],[size],[VM ID]:[VM ID](:[VM ID]...);
the max size of the name is 32 bytes;
the names should not be duplicated;
the mininum value of shared memory region size is 2M;
the value of shared memory region is a power of 2;
the size of share memory region should not extended the size of
available ram.
