ICU-21028 Modifies ICU data generator so that the CLDR version is

no longer added to the .txt data files with the exception of the
root.txt files. This will drastically limit the number of changed
files during a version upgrade because the version change is the
only change in many of the data files.

ICU-21028 Fixed an indent.

ICU-21028 Factor in feedback from review.
