tools: support full-icu by default

Instead of an English-only icudt64l.dat in the repo,
we now have icudt64l.dat.gz with all locales.

- updated READMEs and docs
- shrinker now copies source, and compresses (bzip2) the ICU data file
- configure expects deps/icu-small to be full ICU with a full
compressed data file

 Different Node.js build configurations support different sets of encodings.
-While a very basic set of encodings is supported even on Node.js builds without
