lib: Support localized text of memory_training_desc in ux_locales.c

Browse source 
To support the localized text, we need to get the locale id by vboot
APIs and read raw string content file: preram_locales located at either
RO or RW.

The preram_locales file follows the format:
  [string_name_1] [\x00]
  [locale_id_1] [\x00] [localized_string_1] [\x00]
  [locale_id_2] [\x00] [localized_string_2] ...
  [string_name_2] [\x00] ...

This code will search for the correct localized string that its string
name is `memory_training_desc` and its locale ID matches the ID vb2api
returns. If no valid string found, we will try to display in English
(locale ID 0).
