add armenian language and layouts

[rubentsirunyan]

• add Armenian (hy) as a typing language.
• add 3 layouts, generated from the CLDR keyboard data already vendored in
  packages/keybr-generators/cldr-keyboards-43.0:
• Armenian Phonetic (hy-am-phonetic)
• Armenian Typewriter (hy-am-typewriter)
• Armenian Eastern (hy-am-eastern)

Phonetic is listed first (the default for the language) since its the most widely used layout in Armenia in my experience
and its QWERTY-phonetic mapping is the easiest entry point for learners

Note on և: physical phonetic layouts type the two-character "ԵՎ" on shift+7, which wouldn't fit the per-codepoint character dict. The CLDR definition maps both 7 and shift+7 to the single codepoint և, which is the behavior used here.

The dictionary is built from three Leipzig Corpora Collection word-frequency lists (CC BY): hye_wikipedia_2021_100K, hye_newscrawl_2011_100K, hye-am_web_2015_100K (https://wortschatz.uni-leipzig.de/en/download/Armenian)

Western Armenian (hy-AREVMDA) is intentionally not included: the word list is Eastern Armenian, and the two variants differ substantially.
