[Tests] Increase QMK test coverage (#13789)

* Add per-test keymaps

* Add better trace and info logs for failed unit-tests

* Add layer state assertion with tracing message

* Use individual test binaries configuration options

* Add basic qmk functionality tests

* Add tap hold configurations tests

* Add auto shift tests

* `qmk format-c

* Fix tests
