convert sysfs gpio usage to libgpiod

Updated Chassis Intrusion Sensor monitoring
to use pin name and gpiod APIs. Number based sysfs
framework is deprecated and replaced by descriptor
based gpiod framework. With named gpio pin,
code is more portable provided the device tree
defines GPIO pin name consistently.

This requires device tree change (227661) and
configuration file change (entity-manager/+/28350)

Tested:
Build and run changes together and verified chassis intrusion sensor
value gets updated correctly through D-Bus object.
