There's still a bit of work to do on supporting proper CAPS_LOCK state upon element refocusing, as with switching tabs.

Initial implementation of state key handling is now in place.  The OSK version of state keys acts just like the OSK version of modifiers.  Chiral keyboard now auto-caps all keys when CAPS LOCK is active.

Changed relevant `nextlayer` properties in `kmwLayout` to use kebab-case - AltGr was broken for mobile due to chirality changes.

Yet to do:  state keys, embedded integration.

Implements proper detection of the modifier state both from the OSK and the physical keyboard and also ensures that `osk.clickKey` operates as expected for existing keyboards.

Developed an initial testing framework for the chirality changes, corrected default behavior of buildDefaultLayout when KLS lacks specifications for default layers.

Refactors out the key-102 handling into one of the new helper functions, aiding the readability of osk.buildDefaultLayout.

Heavily refactors osk.buildDefaultLayout in prep for implementation of modifier chirality.  Also defines a lot of nice modifier + state-key constants.
