Ci tweak3 (#2643)

- enable --one-per-family to build 1 board per family, also skip family if board specified in -b also present
- minimize ci run for push event
  - only build one board per family
  - skip hil test on both pi4 and hfp
- full build will be runn for PR event
- IAR always build 1 board per family regardless of event 
- update build.py to optimize make
- remove all setup python since we don't really need it
