This commit adds a new template hook exploreSketch() that allows plugins to efficiently
obtain compile-time known information about the sketch.
The hook is called before setup and is passed a _Sketch
template parameter that wraps two more types Plugins and StaticKeymap, whose static constexpr methods can be used
to explore the registered plugins and the static keymap.

Hook methods can now be templated.
A template parameter type list, a list of template parameters and
a list of dummy template arguments have been added to the
macro arguments used in _FOR_EACH_EVENT_HANDLER.
Non-template hooks pass empty parenthesis for the three newly
introduced macro arguments.

We'd like to be able to run custom code whenever the led mode changes, reliably,
without having to resort to checking the mode every cycle. For this purpose, we
introduce the `onLEDModeChange()` handler plugins can hook into. It will be
called every time `LEDControl.set_mode()` is called, even if that just sets the
mode to the currently active one.

Recently a proposed change to the firmware required a change to one of
the event handlers'/hooks' signatures.
Up to now, we only supported a single overload/implementation of a
event handler of a specific type. This means that changing handler signatures
was only possible by adding a handler method with a similar name and
a different signature like
EventHandlerResult
onKeyswitchEvent(Key &mappedKey, byte row, byte col, uint8_t keyState);
and
EventHandlerResult
onKeyswitchEvent2(Key &mappedKey, KeyAddr key_addr, uint8_t keyState);
As this was regarded as unacceptable confusion of the users of our
programming interface, this commit introduces some changes to the
event handler management.
Important changes:
* handlers can now be overloaded,
* handler signatures can be versioned,
* individual versions can be declared as deprecated,
* we now abort the compile if a handler reimplementation with a bad signature
is found,
* or if two or more handlers with correct signatures are detected that
are furtheron considered as ambiguous.
Impact on resources:
The proposed changes only affect the way things are handled at compile time.
No changes in terms of PROGMEM or RAM are to be expected.

The intent is to make it easier for plugins to detect layer changes and schedule
work accordingly. There event receives no arguments, the current state can
always be queried with `Layer.getLayerState()`, and if a plugin requires the old
state too, they can track that on their own.

Lots of things were already under the `kaleidoscope` namespace, but were in the
"wrong" directory. This big patchset moves everything under `kaleidoscope/`, and
namespaces `Layers_`. There are a few un-namespaced things, but because their
use is so widespread, and they're used so commonly, we don't want to namespace
those (like `handleKeyswitchEvent`), at least not yet.
As a minor side-effect, this moves a few global statics that were once in
`Layers.cpp` into the `Layer_` class itself, for clarity and encapsulation.
Non-namespaced headers that were used outside of Kaleidoscope itself will still
work, but will emit a compile-time warning.
