This follows up on #5489, where we changed the esp32 core pinning to core 0
in order to work around an issue with IDF < 4.2.0. Now that IDF > 4.2.0 is
available, we allow pinning back to core 1, which eliminates some
problematic callback latency with WiFi enabled.
NimBLE is also pinned to core 1 - the same core as MicroPython - when using
IDF >=4.2.
Because "find_package(Python3 ...)" requires at least this version of
CMake. And other features like GREATER_EQUAL and COMMAND_EXPAND_LISTS need
at least CMake 3.7 and 3.8 respectively.

This commit adds support for building the esp32 port with cmake, and in
particular it builds MicroPython as a component within the ESP-IDF. Using
cmake and the ESP-IDF build infrastructure makes it much easier to maintain
the port, especially with the various new ESP32 MCUs and their required
toolchains.
