Update generated binapi to v22.02 & makefile changes

This patch does some small updates to the Makefile.
* `make gen-binapi-from-code` is removed, and moves to
`gen-binapi-local`
* `make build` is patched to build cmd & examples
* `make binapi-generator` to build the api-generator
without other binaries, as they typically require its
output to build.
* `make gen-binapi-local` runs the locally built binapi-generator
to update the local bindings. It expects ${VPP_DIR} to be set and
to point to a local vpp repository checked out with the right version
* `make gen-binapi-internal` runs the locally built binapi-generator
to update the bindings in `internal/testbinapi/binapi2001`

Regarding VPP, notable changes when moving to v22.02 are :
- ControlPing moved from vpe to memclnt
- CliInband went from vpe to vlib
