LibTimeZone+LibUnicode: Generate string data with run-length encoding

Browse source 
Currently, the unique string lists are stored in the initialized data
sections of their shared libraries. In order to move the data to the
read-only section, generate the strings using RLE arrays.

We generate two arrays: the first is the RLE data itself, the second is
a list of indices into the RLE array for each string. We then generate a
decoding method to convert an RLE string to a StringView.
