kata-os-camkes: export C bindings for better CAmkES integration

In particular this exports the CAP_RELEASE flag so there is a single
source for it's definition and KataOS-specific support in the CAmkES
templates is enabled only for KataOS components.

Specific changes:
- adds cbindgen-generated CamkesBindings.h
- adds include of CamkesBindings.h in component cbindgen files
- add a dep on cbindgen.toml in all Makefiles
- update generated interface files
