This method extracts the 2 or 3-letter language code from `OS::get_locale()`,
making it easier for users to identify the "main" language code for users
that might have different OS locales due to different OS or region, but
should be matched to the same translation (e.g. "generic" Spanish).
Fixes#40703.
(cherry picked from commit def99c7baf)
Extra:
- Optimized the debug-only check about why the object is null to determine if it's because it has been deleted (the RC is enough; no need to check the ObjectDB).
- Because of the previous point. the debugger being attached is not required anymore for giving the "Object was deleted" error; from now, it only matters that it's a debug build.
- `is_instance_valid()` is now trustworthy. It will return `true` if, and only if, the last object assigned to a `Variant` is still alive (and not if a new object happened to be created at the same memory address of the old one).
- Replacements of `instance_validate()` are used where possible `Variant::is_invalid_object()` is introduced to help with that. (GDScript's `is_instance_valid()` is good.)
The previous error message incorrectly suggested that any Basis could be fixed by calling get_rotation_quation() or orthonormalize(). This PR points out that only a valid rotation Basis can be fixed in this way.

* Make Undo/Redo menu items disabled when clicking it does nothing.
* Context menu of `TextEdit`
* Context menu of `LineEdit`
* Editor's Scene menu
* Script editor's Edit menu and context menu (for Script and Text)
* Make editor undo/redo log messages translatable.
* Mark `UndoRedo`'s `has_{un,re}do()` methods as `const`.
* Expose `TextEdit`'s `has_{un,re}do()` to scripts since `{un,re}do()` are already available.
Add framework for supporting geometrical occluders within rooms, and add support for sphere occluders.
Includes gizmos for editing.
They also work outside the portal system.
Fixes behavior of these methods:
`InputMap::event_get_action_status`
`InputEvent*::action_match`
Previously when `p_pressed` was `nullptr`, `p_strength` would be set to
`0.0f` regardless of event strength. This affected `InputEventAction` events
processed by `Input.parse_input_event` for example.

This is done by providing API access to app specific directories which don't have any limitations and allows us to bump the target sdk version to 30.
In addition, we're also bumping the min sdk version to 19 as version 18 is no longer supported by Google Play Services and only account of 0.3% of Android devices.
Added one more warning to the hideable warnings. These seem to be benign warnings and are hidden during use in rooms and portals. When used from other areas, only one warning is displayed per run, instead of for every occurrence.
