meta-quanta: gbs: failsafe fan speed control dynamically

1. add acpi-power-state daemon to check the ACPI power
   states from BIOS

2. set failsafe fan speed at different states
   - S0_G0_D0: 90%
   - S5_G2: 40%

   Note:
   this item depends on the commit and will
   add as the patches first in another PR
   https://gerrit.openbmc-project.xyz/38112

3. add gbs-check-host-state.sh to monitor the power state
   D-Bus and then trigger to set fan failsafe speed

4. remove gbs-detect-fan-fail service and unused scripts
   from phosphor-pid-control

5. update read-margin-temp srcrev to avoid nvme temperature
   sensor failed due to nvme SSD not-present
