       * Tag a template literal string for localization.
       *
       * For example:
       *
       * ```ts
       * $localize `some string to localize`
       * ```
       *
       * **Providing meaning, description and id**
       *
       * You can optionally specify one or more of `meaning`, `description` and `id` for a localized
       * string by pre-pending it with a colon delimited block of the form:
       *
       * ```ts
       * $localize`:meaning|description@@id:source message text`;
       *
       * $localize`:meaning|:source message text`;
       * $localize`:description:source message text`;
       * $localize`:@@id:source message text`;
       * ```
       *
       * This format is the same as that used for `i18n` markers in Angular templates. See the
       * [Angular 18n guide](guide/i18n#template-translations).
       *
       * **Naming placeholders**
       *
       * If the template literal string contains expressions, then the expressions will be automatically
       * associated with placeholder names for you.
       *
       * For example:
       *
       * ```ts
       * $localize `Hi ${name}! There are ${items.length} items.`;
       * ```
       *
       * will generate a message-source of `Hi {$PH}! There are {$PH_1} items`.
       *
       * The recommended practice is to name the placeholder associated with each expression though.
       *
       * Do this by providing the placeholder name wrapped in `:` characters directly after the
       * expression. These placeholder names are stripped out of the rendered localized string.
       *
       * For example, to name the `items.length` expression placeholder `itemCount` you write:
       *
       * ```ts
       * $localize `There are ${items.length}:itemCount: items`;
       * ```
       *
       * **Escaping colon markers**
       *
       * If you need to use a `:` character directly at the start of a tagged string that has no
       * metadata block, or directly after a substitution expression that has no name you must escape
       * the `:` by preceding it with a backslash:
       *
       * For example:
       *
       * ```ts
       * // message has a metadata block so no need to escape colon
       * $localize `:some description::this message starts with a colon (:)`;
       * // no metadata block so the colon must be escaped
       * $localize `\:this message starts with a colon (:)`;
       * ```
       *
       * ```ts
       * // named substitution so no need to escape colon
       * $localize `${label}:label:: ${}`
       * // anonymous substitution so colon must be escaped
       * $localize `${label}\: ${}`
       * ```
       *
       * **Processing localized strings:**
       *
       * There are three scenarios:
       *
       * * **compile-time inlining**: the `$localize` tag is transformed at compile time by a
       * transpiler, removing the tag and replacing the template literal string with a translated
       * literal string from a collection of translations provided to the transpilation tool.
       *
       * * **run-time evaluation**: the `$localize` tag is a run-time function that replaces and
       * reorders the parts (static strings and expressions) of the template literal string with strings
       * from a collection of translations loaded at run-time.
       *
       * * **pass-through evaluation**: the `$localize` tag is a run-time function that simply evaluates
       * the original template literal string without applying any translations to the parts. This
       * version is used during development or where there is no need to translate the localized
       * template literals.
       * @param messageParts a collection of the static parts of the template string.
       * @param expressions a collection of the values of each placeholder in the template string.
       * @returns the translated string, with the `messageParts` and `expressions` interleaved together.
