Bundle mulitple familes for self-hosted iar to reduce build time

[hathach]

Describe the PR
IAR Build on self-hosted taking too long (~20mins), reduce the iar build to only family with different enough architecture/usb controller. Also update hardware test on self-hosted to download artifacts to reduce compile time for L4

Didn't know it took such long time. Is it compile time or clone sdk ?

Checkout sumodule take about 30s or so, each build takes 2 minutes for each matrix. Actually, I think the issue is due to the matrix. Matrix scale well with a farm of PC . In our case it hurt the self-hosted since it run one after another on 1 instance (each matrix needs setup/teardown and checkout etc..). Let me try to bundle several family in 1 run, it would possible reduce the time to run

Yes I saw CPU usage is quite low.

Just doubled assigned RAM & Core, after reboot it should be quicker :)

bundled to build everything in one shot, the build time only takes 11 minutes now.

If the cpu usage is still low, it is probably due to my build_family.py script that doesn't do parallel enough. Though it is reasonable for now

that is great, I trigger rebuild to see if we got it faster :)
