The `$path` parameter of `load_script_textdomain()` had a default value of `null`, but would be passed onto the `untrailingslashit()` function without any input validation, even though the latter explicitly only expects/supports a string input.
This commit changes the default value for `$path` to an empty string, and adds an `is_string()` check before passing the value to `untrailingslashit()` to fix the issue at the point where the invalid input is incorrectly (not) validated.
Note: Changing the `untrailingslashit()` function is outside the scope of this commit.
Includes:
* Adding a dedicated unit test for this issue.
* Correcting the default value for `$path` from `null` to an empty string in a few related methods and functions:
* `WP_Dependency::set_translations()`
* `WP_Scripts::set_translations()`
* `wp_set_script_translations()`
* `load_script_textdomain()`
This fix also allows to remove a couple of calls to `expectDeprecation()` in unrelated tests.
Fixes an error when running the test suite:

Previously, when using `switch_to_locale()` all current loaded text domains were unloaded and added to the `$l10n_unloaded` global. This prevented the just-in-time loading for text domains after a switch. The just-in-time loading was also only possible if the translations were stored in `WP_LANG_DIR`. Both issues have been fixed.
* Adds `WP_Textdomain_Registry` to keep track of the language directory paths for all plugins and themes.
* Updates all `load_*_textdomain()` functions to store the path in `WP_Textdomain_Registry`.
* Adds `$locale` parameter to `load_textdomain()` to specify the locale the translation file is for.
* Adds `$reloadable` parameter to `unload_textdomain()` to define whether a text domain can be loaded just-in-time again. This is used by `WP_Locale_Switcher::load_translations()`.
* Extends `_load_textdomain_just_in_time()` to also support text domains of plugins and themes with custom language directories.
* Fixes the incorrect `test_plugin_translation_after_switching_locale_twice()` test which should have caught this issue earlier.
* Adds a new test plugin and theme to test the loading of translations with a custom language directory.
* Deprecates the now unused and private `_get_path_to_translation()` and `_get_path_to_translation_from_lang_dir()` functions.

Since the parameter accepts not only a user's ID, but also a `WP_User` object, `$user` is a more appropriate name, which better aligns with the `$post` parameter of functions that accept a post ID or a `WP_Post` object.
The pre-existing internal `$user` variable which contained a `WP_User` object is renamed to `$user_object` for clarity.

Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.
This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast

This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.
This commit also includes:
* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
* `wp-admin/admin-header.php`
* `wp-admin/admin-footer.php`
* `wp-includes/version.php`
