Turn the `event_handler_hook_add` and `loop_hook_add` aliases into real

In most cases, one only wants a single copy of a hook. On the other hand,
plugins that depend on other plugins, may want to make it easier for the
end-user to use the plugin, and call the setup function of the dependent plugins
too. In case the end-user calls the same setup function, we'd end up with hooks
registered multiple times.
To avoid this, protection against double-registration has been introduced. The
new `event_handler_hook_use` and `loop_hook_use` functions will only allow one
copy of the hook. The `event_handler_hook_append` and `loop_hook_append`
functions will, on the other hand, just append the hooks, and not care about
protection.
The `event_handler_hook_add` and `loop_hook_add` functions are gone, but for the
time being, they are aliases to the `_use` functions, until all plugins have
been updated, and the aliases can be removed.

We want to treat the one-shot keys as active even when they were interrupted -
as long as their state is not cleared. This is because when using isActive from
another plugin, or macro, that is usually in response to a key press that
already sets up `shouldCancel` - yet, the modifier is technically active still!
So `isActive` does not check the to-be-cancelled flag anymore. This makes the

Instead of returning a bool, to signal whether further processing should be

Nevertheless, injecting keys is still possible.
This is not immediately useful for the core firmware, but makes it trivially

Instead of having a primary and a temporary layer, store the state of at

This allows one to reuse a partially transparent layer: set the default,
and the transparent parts will be reused. The numpad layer was updated
accordingly.
Having an interface to the layer switching things also makes it easier

We can't register hooks from constructors, because there is no guaranteed order
in which the objects will be created. So it may well happen that the Keyboardio
object gets created later, and zeroes out everything. Or it gets created first,
and registers the default handler as the first one, making all the others
pointless.
Instead, we create a KeyboardioPlugin class, that has a `begin` method. This is
responsible for setting up the hooks and whatnot. To make things simpler (for
some values of simple), a `Keyboardio.use` method is introduced, which, when
given a NULL-terminated list of plugin object pointers, will call the begin
method of each.
All LED effects and other plugins that used to register a static object now use
an extern, and had their initialization moved to the `begin` method.
The end result is not the nicest thing, but it works. We can try figuring out
something nicer later.

Since macros and other injected keys do not clear the report, we need a way to
release keys. The new `release_key` function does just that, similar to how

Additionally, in handle_key_event_default, baseKey is only looked up if
mappedKey was NoKey. This is so that hooks can defer to this function,
via handle_key_event, setting their own mappedKey, without having to
worry about setting a row/col that would map to a special key on the

To make replacing work sanely, we first NULL out both the eventHandlers
and loopHooks arrays in the Keyboardio_ constructor. This allows the
replace functions to just run through the whole array, and either see
hook pointers there, or NULL. So they don't need to be afraid of garbage
being there.
This makes the replacing very easy: run through the array, and replace
the first occurrence of the old hook with the new. This further
simplifies addition: the old hook we pass in, will be NULL. If we run
out of space, it silently fails, like before.
Replacing hooks is important for cases where one wants to build features
that can be toggled off, or their behaviour otherwise changed at
run-time. In this case, the most efficent way is to replace the hook,
which is what these new helpers allow us to do.

There are scenarios where one would want to inject a keycode into the
event handler chain, restart the processing from scratch, but with a
keycode different than what the lookup would normally yield. For
example, with one-shot modifiers, a feature one may wish is to be able
to turn the one-shotness off, and have them act as normal modifiers.
This is easily done, if we can remove the one-shot markup, and let the
event handler process the resulting code as-is.
This makes that possible: in a custom event handler, just call
handle_key_event() with the first argument set to the desired code, and
the rest left unchanged. This makes it possible to inject events: not
just register keycodes with the HID, but inject synthetic events,
something much more powerful.
