rp2,esp32,extmod: Implement UPDATE_SUBMODULES in CMake.
Rather than having Make calling CMake to generate a list of submodules and
then run a Make target (which is complex and prone to masking other
errors), implement the submodule update logic in CMake itself.
Internal CMake-side changes are that GIT_SUBMODULES is now a CMake list,
and the trigger variable name is changed from ECHO_SUBMODULES to
UPDATE_SUBMODULES.
The run is otherwise 100% a normal CMake run now, so most of the other
special casing can be removed.
