The metairq sample sometimes failed due to stuck because it has a
potential race when recording the latencies. The previous solution
checks whether the stats.mirq greater than MAX_EVENT. But stats.mirq
might also have a race here. So we change to check the msg sequence,
its correctness ensured by the kernel's message queue.
And also remove the spinlock in previous fix because tests only use
1 CPU, no need to add this. It also improves the fix for #40889,
to prevent test failed sporadically on acrn_ehl_crb and ehl_crb.
Fix#42874.

The samples/kernel/metairq_dispatch runs failed on acrn_ehl_crb
due to the potential race condition in accessing the global stat
data. Add a spinlock to prevent this.
Fixes#40889

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

Normally main.c file doesn't have a header, beacuse it doesn't need to
be declared to other modules.
And in this sample it makes more sense to use name msgdev.h instead of
main.h as the header file for msgdev.c.
