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.

Ivshmem device defines four registers including Interrupt Mask, Interrupt

is required. The latter two are used for interrupts and will be implemented
in the future.

it can be used to find an ivshmem device through pci_vdev.

while in cpuid_subleaf:
*eax = leaf;
*ecx = subleaf;
eax and ecx point to the same location,
When deep into asm_cpuid, it's input value will be 0x0U and 0x0U.
but the expected input value is 0x1U and 0x0U.
This case will return CPUID.00H:EDX, which is the wrong answer.

THEN DisplayModel = (Extended_Model_ID « 4) + Model_ID;

This patch will move the VM configuration check to pre-build stage,
a test program will do the check for pre-defined VM configuration
data before making hypervisor binary. If test failed, the make
process will be aborted. So once the hypervisor binary is built
successfully or start to run, it means the VM configuration has
been sanitized.
The patch did not add any new VM configuration check function,
it just port the original sanitize_vm_config() function from cpu.c
to static_checks.c with below change:
1. remove runtime rdt detection for clos check;
2. replace pr_err() from logmsg.h with printf() from stdio.h;
3. replace runtime call get_pcpu_nums() in ALL_CPUS_MASK macro
with static defined MAX_PCPU_NUM;
4. remove cpu_affinity check since pre-launched VM might share
pcpu with SOS VM;
The BOARD/SCENARIO parameter check and configuration folder check is
also moved to prebuild Makefile.
