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.

fix helix/rev2:edvorakjp build error (#16433)

'helix/rev2/keymaps/edvorakjp' was no longer buildable due to changes made by #14864.
The reason is that the prototype of `oled_task_user()` was changed in keymaps/edvorakjp/oled.c, but keymaps/edvorakjp/oled.h was not changed.
Therefore, I modified the prototype in keymaps/edvorakjp/oled.h.
