Reland "Rename translation files for android_keyboard_accessory_strings.grd"

This is a reland of ab4cac496a525970f6bb3bf9bb424499c45471d4

Original change's description:
> Rename translation files for android_keyboard_accessory_strings.grd
> 
> When running the translate.py script, it fails because the translation
> files have an incorrect name:
> android_keyboard_accessory_strings.grd: invalid xtb name:
>  "android_chrome_keyboard_accessory_strings_am.xtb. xtb name must be
>   android_keyboard_accessory_strings_<lang>.xtb where <lang> is the
>   language code."
> 
> This CL drops the "chrome_" from all translation names to resolve this.
