feat(linux.gpio): Added support to gpio symlinks #5246

This PR adds the support to symlinks in the jdk.dio.properties file.

Related Issue: This PR fixes/closes N/A

Description of the solution adopted: The current implementation of the GPIOService parses the jdk.dio.properties and reads the GPIO indexes/numbers. The entry looks like:

123 = deviceType: gpio.GPIOPin, pinNumber:123, name:GPIO123

This PR allows to set a symlink instead of a pin number in the configuration file:

/dev/dio1 = deviceType: gpio.GPIOPin, name:DIGITAL_INPUT1

where the /dev/dio1 points to /sys/class/gpio/gpioXYZ. The GPIOService implementation will follow the symlink and read the pin number (XYZ) from the path.
