* To avoid spurious CDC ACM instances when usint CDC ACM for something
other than logging, move to the approach used by Zephyr of using a
snippet to redirect console output to a CDC ACM node added by the
snippet. Remove all the existing static CDC ACM nodes.
* Add new `zmk-usb-logging` snippet that mirrors the upstream
`cdc-acm-logging` snippet, but still does our extra USB logging
configuration.
* Updated logging docs accordingly.

Removed "label" properties which no longer have any function.
Labels are still used as layer names and as identifiers for sending
behaviors between sides of a split keyboard, so those have been left
alone for now.
* Previous version of multiple overrides of the default value of ZMK_USB
were problematic. Move to using board _defconfig files for the
defaults for those, along with proper `depends on` for ZMK_USB that
accounts for split and split roles.
Aligns *.h and *.c to underscore naming convention.
These were kept (with warnings) for backwards compatibility with external boards/shields:
- kscan-mock.h
- matrix-transform.h
They should be removed in the future.
