JS: Rename getTargetFile to getImportedFile and remove its deprecated name clash

'getTargetFile' was originally named to avoid the clash with 'getImportedFile' from a subclass. But we now just merge the two predicates.

-   * This predicate implements the specification of
-   * [`require.resolve`](https://nodejs.org/api/modules.html#modules_all_together),
-   * modified to allow additional JavaScript file extensions, such as `ts` and `jsx`.
-   *
-   * Module resolution order is modeled using the `priority` parameter as follows.
-   *
-   * Each candidate folder in which the path may be resolved is assigned
-   * a priority (this is actually done by `Module.searchRoot`, but we explain it
-   * here for completeness):
-   *
-   *   - if the path starts with `'./'`, `'../'`, or `/`, it has a single candidate
-   *     folder (the enclosing folder of the module for the former two, the file
-   *     system root for the latter) of priority 0
-   *   - otherwise, candidate folders are folders of the form `<prefix>/node_modules`
-   *     such that `<prefix>` is a (not necessarily proper) ancestor of the enclosing
-   *     folder of the module which is not itself named `node_modules`; the priority
-   *     of a candidate folder is the number of steps from the enclosing folder of
-   *     the module to `<prefix>`.
-   *
-   * To resolve an import of a path `p`, we consider each candidate folder `c` with
-   * priority `r` and resolve the import to the following files if they exist
-   * (in order of priority):
-   *
-   * <ul>
-   * <li> the file `c/p`;
-   * <li> the file `c/p.{tsx,ts,jsx,es6,es,mjs,cjs}`;
-   * <li> the file `c/p.js`;
-   * <li> the file `c/p.json`;
-   * <li> the file `c/p.node`;
-   * <li> if `c/p` is a folder:
-   *      <ul>
-   *      <li> if `c/p/package.json` exists and specifies a `main` module `m`:
-   *        <ul>
-   *        <li> the file `c/p/m`;
-   *        <li> the file `c/p/m.{tsx,ts,jsx,es6,es,mjs,cjs}`;
-   *        <li> the file `c/p/m.js`;
-   *        <li> the file `c/p/m.json`;
-   *        <li> the file `c/p/m.node`;
-   *        </ul>
-   *      <li> the file `c/p/index.{tsx,ts,jsx,es6,es,mjs,cjs}`;
-   *      <li> the file `c/p/index.js`;
-   *      <li> the file `c/p/index.json`;
-   *      <li> the file `c/p/index.node`.
-   *      </ul>
-   * </ul>
-   *
-   * The first four steps are factored out into predicate `loadAsFile`,
-   * the remainder into `loadAsDirectory`; both make use of an auxiliary
-   * predicate `tryExtensions` that handles the repeated distinction between
-   * `.js`, `.json` and `.node`.
