CLI: Validate JSON keymap input (#16261)

* Fix schema validator

It should use the passed schema.

* Add required attributes to keymap schema

* Rework subcommands to validate the JSON keymaps

The 'compile', 'flash' and 'json2c' subcommands were reworked to add
JSON keymap validation so error is reported for non-JSON and
non-compliant-JSON inputs.

* Fix required fields in keymap schema

* Add tests

* Fix compiling keymaps directly from keymap directory

* Schema should not require version for now.
