This replaces the `Layer.live_composite_keymap_[]` cache with a representation
of the keyboard's current state as an array of `Key` objects, one per key on the
keyboard. In this new array, an idle key will have the value `Key_Transparent`,
and a pressed key will have the value of whatever key it's currently mapped to
in the keymap (or whatever value the active set of plugins has assigned to
it). A value of `Key_NoKey` will mask that key until it is released.
If a plugin returns `ABORT` from its `onKeyswitchEvent()` handler, that means
that the keymap cache should not be updated. It's especially important to have
this occur after plugins like OneShot and Qukeys, where the key can stay
active (or become active) after the physical keyswitch has been released.

To make it easier to configure which HID implementation - and which parts of it
- a particular board uses, we turn our current HID facade (`kaleidoscope::hid`)
into a proper, Props-supported driver. This also allows us to get rid of the
`Kaleidoscope-HIDAdaptor-KeyboardioHID` library.

This was done to enable separate inclusion of the central runtime
class without having to include the central header
kaleidoscope/Kaleidoscope.h which used to pull in a lot of stuff that is
not required in many compilation units.
The new class `Runtime_` lives in namespace kaleidoscope its singleton
instance is `kaleidoscope::Runtime`. It is now only available internally
in library Kaleidoscope but not from the sketch.
The original class name `Kaleidoscope_` in global scope has been deprecated.
The original instance name `Kaleidoscope` in global scope has been
preserved to be used by end users in their sketches.

Unions are a C-reminiscense that are better avoided in modern C++.
They cause specific problems due to their nature of representing
independent types. The way they are used in Kaleidoscope, they
can easily be replaced by a class.
This enables it to properly work with Key objects in constexpr context
where with the old union-based implementation the compiler reported
errors when one Key was constructed based on a key_code/flags pair and
another one through raw-data. In such a case, the compiler assumes that
both Key instances represent something entirely different. This is
because unions were never meant for type conversions and the C++
standard considers their use for that purpose as undefined behavior.
The new class provides accessor methods for raw-data access and for
key_code/flags-data access.
This is a breaking change as it is is not possible to replace direct
member access patterns like
key.raw = 0xFFFF;
based on the raw-accessors.
For the .keyCode and .flags members, proxy objects are used
to enable the generation of suitable deprecations warnings.
All direct access via .raw, .keyCode and .flags have been replaced
throughout Kaleidoscope.
Information on how to upgrade is provided in UPGRADING.md

Instead of having to define `HARDWARE_IMPLEMENTATION` to the class name of the
device, and define `KeyboardHardware` from within the plugin, let all devices
set `kaleidoscope::Device` to their own class via a typedef. Furthermore,
instead of `KeyboardHardware`, use `Kaleidoscope.device()` instead. This makes
device plugins a little bit simpler, and our naming more consistent.
Because some parts of the firmware need to access the device object before the
`Kaleidoscope` object is available, we can't make it a member of that. For this
reason, the device object is `kaleidoscope_internal::device`, and
`Kaleidoscope.device()` wraps it. In general, the wrapper should be used. But if
access to the device is required before `Kaleidoscope` is available, then that's
also available.
The `Kaleidoscope` object grew a few more wrappers: `storage()` and
`serialPort()`, so that one doesn't need to use `Kaleidoscope.device()`
directly, but can use the wrappers, which are noticably shorter to write.

An `EPHEMERAL` keyswitch event is one that gets ignored by updates to
`live_composite_keymap_[]`, and thus doesn't change the keymap at all. This is useful for
a plugin that needs to retain its own key type in the keymap in order to do something
particular when it toggles off, but needs to inject an event with a different `Key` value,
with real key coordinates.

If `handleKeyswitchEvent()` is called with a `mappedKey` other than `Key_NoKey`, update
`live_composite_keymap_` with the specified `mappedKey` instead of doing a keymap lookup
on active layers. This allows a plugin to call `handleKeyswitchEvent()` and specify what
the `Key` value should be, and not have to separately track what value to change it to
every cycle.
This is especially important when there's a layer change. In particular, this is the
simplest way to allow Qukeys to use `ShiftToLayer()` keys that work properly.
Fixes#501.

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.
