lcd: Renamed 'i2clcd' library to 'lcd'

All other upm library directories match their corresponding library
name, the i2clcd was an outlier which caused problems for CMake and
testing.

    * Replaced usage of i2clcd with lcd
    * Renamed source files and examples
    * Updated examples to use correct class
    * Updated documentation where necessary (left changelog sections)
