The underlying OS (the ESP-IDF) uses it's own internal errno codes and so
it's simpler and cleaner to use those rather than trying to convert
everything to the values defined in py/mperrno.h.
It's now replaced by cmake/idf.py. But a convenience Makefile is still
provided with traditional targets like "all" and "deploy".

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.

This allows changing the baudrate of the UART without reinitialising it
(reinitialising can lead to spurious characters sent on the TX line).

On i.MX the SysTick IRQ cannot wake the CPU from a WFI so the CPU was
blocked on WFI waiting for USB data in mp_hal_stdin_rx_chr() even though it
had already arrived (because it may arrive just after calling the check
tud_cdc_available()). This commit fixes this problem by using SEV/WFE to
indicate that there has been a USB event.
The mp_hal_stdout_tx_strn() function is also fixed so that it doesn't
overflow the USB buffers.

So that all MicroPython ports that use tinyusb use the same version. Also
requires fewer submodule checkouts when building rp2 along with other ports
that use tinyusb.
