Support for Nintendo Switch (#4491) 
* WIP support for Nintendo Switch

* OpenAL is usable

* Remove some debug code, add manual crash when DEBUG_NXLINK is on

* Remove more debug logs

* Support touch, account name detection, language detection. Remove resolution settings

* Stylistic changes

* SFXManager: update on main thread

* Add build script, remove crypto.hpp changes, disable opengl recorder on switch

* make: use sudo where needed, libs=>lib, portlib=>portlibs

* make: build harfbuzz with freetype

* main: remove DEBUG_NXLINK

* socket_address: this comment is no longer relevant

* Fix indentation in SDL, remove extra debug logs from InputManager

* InputManager: make log debug, not info

* CMakeLists: add mbedtls include dirs on switch

* main: deinitialize stuff

* main_loop: fix format

/** Run the actual main loop.
* The sequnce in which various parts of STK are updated is:
* - Determine next time step size (`getLimitedDt`). This takes maximum fps
* into account (i.e. sleep if the fps would be too high), and will actually
* slow down the in-game clock if the fps are too low (if more than 3/60 of
* a second have passed, more than 3 physics time steps would be needed,
* and physics do at most 3 time steps).
* - if a race is taking place (i.e. not only a menu being shown), call
* `updateRace()`, which is a thin wrapper around a call to
* `World::updateWorld()`:
* - Update history manager (which will either set the kart position and/or
* controls when replaying, or store the current info for a replay).
* This is mostly for debugging only (though available even in release
* mode).
* - Updates Replays - either storing data when not replaying, or
* updating kart positions/control when replaying).
* - Calls `WorldStatus::update()`, which updates the race state (e.g.
* go from 'ready' to 'set' etc), and clock.
* - Updates the physics (`Physics::update()`). This will simulate all
* physical objects for the specified time with bullet.
* - Updates all karts (`Kart::update()`). Obviously the update function
* does a lot more than what is described here, this is only supposed to
* be a _very_ high level overview:
* - Updates its rewinder (to store potentially changed controls
* as events) in `KartRewinder::update()`.
* - Calls `Moveable::update()`, which takes the new position from
* the physics and saves it (and computes dependent values, like
* heading, local velocity).
* - Updates its controller. This is either:
* - an AI using `SkiddingController::update()` (which then will
* compute the new controls), or
* - a player controller using `PlayerController::update()`, which will
* handle smooth steering (in case of digital input devices steering
* is adjusted a bit over time to avoid an instant change from all
* left to all right). Input events will be handled when updating
* the irrlicht driver later at the end of the main loop.
* - Updates kart animation (like rescue, ...) if one is shown atm.
* - Update attachments.
* - update physics, i.e. taking the current steering and updating
* the bullet raycast vehicle with that data. The settings are actually
* only used in the next frame when the physics are updated.
* - Updates all cameras via `Camera::update()`. The camera position and
* rotation is adjusted according to the position etc of the kart (and
* special circumstances like rescue, falling).
* - Updates all projectiles using the projectile manager. Some of the
* projectiles are mostly handled by the physics (e.g. a cake will mainly
* check if it's out of bounds), others (like basket ball) do all
* their aiming and movement here.
* - Updates the rewind manager to store rewind states.
* - Updates the music manager.
* - Updates the input manager (which only updates internal time, actual
* input handling follows late)
* - Updates the wiimote manager. This will read the data of all wiimotes
* and feed the corresponding events to the irrlicht event system.
* - Updates the STK internal gui engine. This updates all widgets, and
* e.g. takes care of the rotation of the karts in the KartSelection
* screen using the ModelViewWidget.
* - Updates STK's irrlicht driver `IrrDriver::update()`:
* - Calls Irrlicht's `beginScene()` .
* - Renders the scene (several times with different viewport if
* split screen is being used)
* - Calls `GUIEngine::render()`, which renders all widgets with the
* help of Irrlicht's GUIEnvironment (`drawAll()`). This will also
* handle all events, i.e. all input is now handled (e.g. steering,
* firing etc are all set in the corresponding karts depending on
* user input).
* - Calls Irrlicht's `endScene()`
