Rework rp2040 examples and CMake build:

	- Examples should be CMake buildable from their own subdirectory; such a build will error out based on
	  matching .skip.MCU_xxx or a mismatched .only.MCU_
	- It should be possible to build from a higher level and use .skip.MCU_ and .only.MCU_ to filter which
          examples get built
	- The intention is for the CMakeLists.txts in the examples to be non family specific and without MCU based IFs. I have
          started this work, but am not really sure the state of the esp32 stuff; in any case the plan is to have
          everything encapsulated in the FAMILY/family.cmake
	- pico_examples now just includes examples/device/CMakeLists.txt and examples/host/CMakeLists.txt directly, as they
	  also build correctly when included from there.
Note that .skip.MCU_ for esp32 in the directories it wasn't previously avaiable has not been added, as the .skip is common to the regular Makefile builds also. It isn't clear whether these examples should build for esp32, but if not .skip should be added.
