BJoystick: Fix fJoystickInfo initialization.

joystick_info contains BLists which initialize themselves upon new(),
and Clang warned (correctly) that using memset() overwites that, as well as
RTTI and other data that they contain. So instead, only memset the first
part of the struct, and then manually initialize the other members.

Fixes #14217.

Specify that we support variable mode, which will cause drivers to switch to
that mode when they support it. Right now there is only usb_hid though. With
this commit controllers with an arbitrary number of axes, hats and buttons are
now supported by BJoystick and by the BJoystick <-> driver protocol as well as
by usb_hid (usb_hid doesn't yet have support for hats though).

* Replace the fixed size extended_joystick structure with a variably sized one
inside BJoystick.
* Add joystick_module_info flag to communicate support for variably sized reads.
* The variably sized data structure is set up to describe either the actual
amount of data, when variably sized reads are supported by the driver, or it
is set up so that it exactly matches the data layout of the extended_joystick
structure. This allows us to support both as input data, while only needing to
care about a single format inside BJoystick. Convenience pointers allow the
data to be retrieved without additional overhead or extra logic.
* Add some sanity checks and ensure some boundaries when dealing reading data
from the variably sized structure (as there might not be any buttons, hats,
axis at all now).
* Ensure that the extended_joystick structure doesn't change in size due to
padding by making it _PACKED (it wasn't padded though).

This is still supposed to work exactly as before. However, it opens up the
possibility to actually support arbitrary controllers with arbitrary axis, hat
and button counts. It therefore allows to actually deliver what the BJoystick
API was designed to handle all along.

Introduce a BJoystick::GetButtonValues() function that aligns with the other
Get*Values() functions but retrieves an arbitrary amount of button states using
a boolean array. This overcomes the 32 button limitation on the API side. Right
now the function does simply set the first 32 states from the button bitmap, as
the BJoystick to driver interface hasn't been adapted yet.

Cleanup of the _BJoystickTweaker:
* Include sorting, header style, macro naming, variable naming, spacing, ...
* Some simplifications, early returns and the like.
* The device name list items were allocated with new but deleted with free. The
whole private BJoystick list being modified by a friend class is dubious
though and should be reworked. Ideally node monitoring would be implemented
so that the list can be re-populated on demand instead of scanning through
every time.
