Fixes#6455.
This involved adding an extra hint to the data passed into the lexical
model layer, being the CasingForm that the current layer wants to use.
Given there are several entry points to the lexical model layer, this
meant a few places where we needed to check the current layer.
I refactored the very long function `InputProcessor.processKeyEvent` to
extract out the `buildAlternates` function. There should be no
functional changes to the `buildAlternates` code. But it makes
`processKeyEvent` significantly easier to read.

Fixes#6005.
If a key has no default behavior, and the expectation is to trigger the
key default, then set the output behavior to null, so that the caller
will do the action.
This fixes a regression in #5553, which handled the situation where a
rule was triggered but then default output was expected (common example
is final sigma transform only when a word is finished).
The regression resulted in suggestions rotating unexpectedly when
pressing a modifier key.
Fixes#6364.
Removes `&layerChanged` and adds `&newLayer` and `&oldLayer` system
stores with the additional nuances around values as described in #6364.
The Caps Lock change I made in the previous commit broke
desktop Caps Lock handling. The fix was a little more
convoluted. Turns out that _UpdateVKShift is also pretty
crufty. I simplified it, removing dead code.
Selecting the new Caps Lock `caps` layer was not correctly setting the
layer state in the key event to `caps`, which caused Caps Lock rules
to fail to match.
