ceb7b11f16 configure_input_player: Change "Defaults" button behavior
RestoreDefaults() now restores the selected devices' mappings using UpdateMappingWithDefaults().
This allows us to move the keyboard mapping from RestoreDefaults() to UpdateMappingWithDefaults().

With this, the "Input Devices" combobox should accurately reflect the input device being used and disallows inputs from other input devices unless the input device is set to "Any".

2f852f182a sdl_impl: Fix controller reconnection issues
It turns out that after a controller is disconnected, there is a chance that events from the previous controller are sent/processed after it has been disconnected.
This causes the previously disconnected controller to reappear as connected due to GetSDLJoystickBySDLID() emplacing this controller back to the map.

Fix this by only returning an SDLJoystick if and only if it exists in the map.

7b3f5845d2 sdl_impl: Erase the SDLJoystick entry after removing a controller
Previously, disconnecting a controller still leaves a null SDLJoystick entry within the vector of SDLJoysticks mapped by GUID.
When a DirectInput device of the same GUID is reconnected, it adds that device to a new port causing non-detectable input.
Furthermore, opening the "Configure" menu would cause yuzu to crash since it first tries to resolve the name of a null SDLJoystick entry that was not removed.
Resolve this by properly erasing the SDLJoystick entry from the vector.

9e1b0af259 input_common: Eliminate most global state
Abstracts most of the input mechanisms under an InputSubsystem class
that is managed by the frontends, eliminating any static constructors
and destructors. This gets rid of global accessor functions and also
allows the frontends to have a more fine-grained control over the
lifecycle of the input subsystem.

This also makes it explicit which interfaces rely on the input subsystem
instead of making it opaque in the interface functions. All that remains
to migrate over is the factories, which can be done in a separate
change.

Allows reporting more cases where logic errors may exist, such as
implicit fallthrough cases, etc.

We currently ignore unused parameters, since we currently have many
cases where this is intentional (virtual interfaces).

While we're at it, we can also tidy up any existing code that causes
warnings. This also uncovered a few bugs as well.

230ac6a4e8 input_common/udp: Fix Linux build by using a backwards compatible way of error checking
Should fix https://github.com/yuzu-emu/yuzu/issues/3487.

error_code::failed is a function which has been introduced in Boost 1.69.
This version of boost hasn't landed in most major distros yet.

5c61e0ba39 input_common/udp: std::move SocketCallback instances where applicable
std::function is allowed to heap allocate if the size of the captures
associated with each lambda exceed a certain threshold. This prevents
potentially unnecessary reallocations from occurring.
