Note: LatinIMETests for Turkish layout alongside other QWERTY layouts
will fail due to LineageOS team kept additionalmorekeys such as
asterisk, hashtag, ampersand etc. but pulled tests from official
upstream which dropped additionalmorekeys from all Latin keyboard
layouts (except numerals at the top row).
