Changes in this commit:
- Manifest include's now use the directory path where possible (no longer
necessary to include the manifest.py file explicitly).
- Add manifest.py for all drivers and components that are referenced by
port/board manifests.
- Replace all uses of freeze() with package()/module(), except for port and
board modules.
- Use opt=3 everywhere, for consistency and to reduce code size.
- Use require() instead of include() for all micropython-lib references.
- Remove support for optional board-level manifest.py in mimxrt port, to
make it behave the same as other ports (the board must set
FROZEN_MANIFEST to a custom manifest.py, which can optionally include the
default, port-level manifest).
- Also reinstates modules that were accidentally removed from the esp8266
512k build in fbe9417b90.

Having two separate manifests is confusing. It's simpler to have the daily
builds use the same configuration as the stable, release builds.

The ntptime module was previously only included in the ESP8266 port. This
commit factors that module out into the extmod directory, makes it support
different epochs, and includes it in the rp2 port.
Allow esp32.ULP.load_binary() to use the maximum amount of memory available
again, which is 2040 bytes unless MICROPY_HW_RTC_USER_MEM_MAX is
customized.

These boards do not build with IDF v4.4 because the section .iram0.text
does not fit in region iram0_0_seg. Enabling SPIRAM increases the code
size so use -Os instead of -O2 to build these boards.
Fixes issue #8260.
Some S2/S3 modules don't use the native USB interface but instead have an
external USB-UART. To make the GENERIC_S3/S3 firmware work on these boards
the UART REPL is enabled in addition to the native USB CDC REPL.
Fixes issues #8418 and #8524.

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.
Rework the ADC implementation to follow the improved ADC/ADCBlock API.
This adds support for calibrated voltage readings and the ADC2 block. The
ADC API is backwards compatible with what it was before this change.
Resolves#6219.
This board has only 2MiB of flash so the build needs to be reduced in size
to fit. Commit 549448e8bb made all boards
build with -O2 by default (for performance) so this overrides that default.

Default SPI pins are now correctly assigned by machine_hw_spi.c even for S2
and S3. mpconfigboard.h files define defaults with flipped SPI(1) and
SPI(2) to workaround a bug in machine_hw_spi.c - the bug is fixed.

This will be used by https://micropython.org/download/ to generate the
full listing of boards and firmware files.
Optionally supports a board.md for additional customisation of the
download page, as well as deploy.md for flashing instructions.

This commit enables some significant optimisations for esp32:
- move the VM to iRAM
- move hot parts of the runtime to iRAM (map lookup, load global/name,
mp_obj_get_type)
- enable MICROPY_OPT_LOAD_ATTR_FAST_PATH
- enable MICROPY_OPT_MAP_LOOKUP_CACHE
- disable assertions
- change from -Os to -O2 for compilation
It's hard to measure performance on esp32 due to external flash and
hardware caching. But this set of changes improves performance compared to
master by (on a TinyPICO with the GENERIC build, using IDF 4.2.2, running
at 160MHz):

Five tests have more than 3x speed up (200%+).
The performance of the tests bm_fft, bm_pidigits and misc_aes now scale
with CPU frequency (eg changing frequency to 240MHz boosts the performance
of these by 50%), which means they are no longer influenced by timing of
external flash access. (The viper_call* tests did previously scale with
CPU frequency, and they still do.)
Turning off assertions reduces code size by about 80k, and going from -Os
to -O2 costs about 100k, so the net change in code size (for the GENERIC
board) is about +20k.
If a board wants to enable assertions, or use -Os instead of -O2, that's
still possible by overriding the sdkconfig parameters.

Add a new board type for ESP32-C3 revision 3 and up that implement the USB
serial/JTAG port on pin 18 and 19. This variant uses the USB serial for
programming and console, leaving the UART free.
- Pins 18 and 19 are correctly reserved for this variant. Also pins 14-17
are reserved for flash for any ESP32-C3 so they can't be reconfigured
anymore to crash the system.
- Added usb_serial_jtag.c and .h to implement this interface.
- Interface was tested to work correctly together with webrepl.
- Interface was tested to work correctly when sending and receiving
large files with ampy.
- Disconnecting terminal or USB will not hang the system when it's
trying to print.
Dynamically generate/loaded native code (eg from @micropython.native or
native .mpy files) needs to be able allocate from IRAM, and the memory
protection feature must be disabled for that to work. Disabling it is
needed to get native code working on ESP32-S2 and -C3.

ATOM is a very small ESP32 development board produced by M5Stack, with a
size of 24mm * 24mm, with peripherals such as WS2812, IR, button, MPU6886
(Only Matrix), and 8 GPIO extensions. It also has a plastic shell.
Improvements made:
- PSRAM support for S2
- partition definition for 16MiB flash
- correct ADC and DAC pins
- correct GPIO and IRQ pins
- S3 components in CMakeLists
