corsola: zephyr project organization

Firstly, renames the .dts, .conf and places to the project folder.

For the components excluding battery and led, rename them by the rule:

- kingler -> npcx
- krabby -> ite
- prj.conf -> program.conf
- prj_npcx|ite.conf -> npcx|ite_program.conf
- move prj_*.conf to $project/project.conf
- rename .dts to .dtsi
- move consolidate project dts to $project/project.overlay

There will be following CLs for the next step organizing.
- clean up krabby family dtsi sharing
- add CMakeLists.txt for projects
