slide: Added slide potentiometer sensor C source

Added the C source for the flex sensor with necessary changes to cmake,
examples, and docs.

    * Renamed all files with groveslide to slide
    * Replaced all instances of groveslide with slide
    * Added C source for slide sensor
    * Updated all cmake files
    * Added C example for slide sensor
    * Split out slide sensor from grove library
