lib: Refactor ux_locales_get_text API

This patch refactors the `ux_locales_get_text` API to handle fallback
text (English) internally, rather than relying on the caller. It
introduces message IDs for lookups, enabling the API to locate both
the UX locale name and fallback text based on the ID.

- ux_locales_get_text: Get UX locales msg based on locales name.
- ux_locales_get_text_by_id - Get UX locales msg based on msg ID.

`ux_locales_get_text_by_id` retrieve fallback text message depending
upon the msg ID incase UX locales not available. `ux_locales_get_text`
API now takes an additional argument as fallback text if provided,
otherwise return NULL.

This centralizes fallback handling and simplifies adding future
messages without per-SoC duplication.
