This introduces `ToggleLayer(n)` and `MomentaryLayer(n)`, which make it
easier to switch to layers higher than five, and allow one to use enum
values in place of `n`, such as: `ToggleLayer(NUMPAD)`,
`MomentaryLayer(FUNCTION)`.

Currently, if kaleidoscope-builder fails to find a sketch file, the
resulting error message is very confusing and unhelpful. This commit
makes it more straightforward and helpful.
We want to start with a pre-cached state, so we have both less work to do when
keys are first pressed, and so that plugins that rely on the live composite
state will work reliably too.

For all cases outside of Kaleidoscope itself, we are good with the value of
`highestLayer`, and do not need to re-scan the layer state. For this reason -
upon @obra's suggestion - rename `Layer.highest()` to `Layer.top()`, and the old
`Layer.top()` to `Layer.updateHighestLayer()`, and make the latter private, and
update the `highestLayer` member variable instead of returning the number.

`layer_getKey` was introduced in 6d641e7fc5, by
mistake, it was never implemented. Remove it now to avoid any possible
confusion.

Sometimes we would like to know the highest active layer, which is available in
the `highestLayer` private variable, and via `.top()` too. We do not want to
make `highestLayer` public, because we want to be the only ones changing it. And
while `top()` gets us roughly the same information, it does so at a cost. For a
lot of purposes, the cached `highestLayer` would be perfectly adequate.
The new `Layer.highest()` accessor does just this.

Refactor the momentary layer handling part of `handleKeymapKeyswitchEvent`.
Instead of a bunch of ifs that are increasingly hard to follow, use a switch
based on the target layer, and branch out depending on `keyState` from there.
Makes it easier to follow what happens.

If we have two keys on our keymap that momentarily go to the same layer (which
is the case for the factory firmware), we hold both, and release one, we want
the layer to remain active still.
To this effect, in `handleKeymapKeyswitchEvent` we will handle the case when a
momentary layer key is pressed, but not toggled on (that is, it is held): if it
is not a next/previous switch, we re-activate the layer if it wasn't on.
This fixes#154, thanks to @ToyKeeper for the report.

With the new implementation, there are two lookup functions, because we have two
caches, and different parts of the firmware will want to use either this or
that (or perhaps both, in rare cases).
First of all, we use caches because looking up a key through all the layers
is costy, and the cost increases dramatically the more layers we have.
Then, we have the `effectiveKeymapCache`, because to have layer behaviours
we want, that is, if you hold a key on a layer, release the layer key but
continue holding the other, we want for the layered keycode to continue
repeating. At the same time, we want other keys to not be affected by the
now-turned-off layer. So we update the keycode in the cache on-demand, when
the key is pressed or released. (see the top of `handleKeyswitchEvent`).
On the other hand, we also have plugins that scan the whole keymap, and do
things based on that information, such as highlighting keys that changed
between layers. These need to be able to look at a state of where the
keymap *should* be, not necessarily where it is. The `effectiveKeymapCache`
is not useful here. So we use a `keymapCache` which we update whenever
layers change (see `Layer.on` and `Layer.off`), and it updates the cache to
show how the keymap should look, without the `effectiveKeymapCache`-induced
behaviour.
Thus, if we are curious about what a given key will do, use `lookup`. If we
are curious what the active layer state describes the key as, use
`lookupUncached`.

Only update the keymap cache if the layer state changed for real. If we turn a
layer that was already on, on again, we do not need to update. Same for turning
them off.
This results in a tiny speedup if we have code that calls `Layer.on()` or
`Layer.off()` often.

When we change layers, we want to update the key cache for the whole keyboard,
so that LED modes and other things that depend on all keys being up-to-date will
work as expected.
Do the same at `Kaleidoscope.setup` time, so we start with a good state too.
This fixeskeyboardio/Kaleidoscope-Numlock#7.
