Existing C code in `main.c` only mounts a flash filesystem if one exists,
and doesn't do anything if the 'storage' partition is not formatted.
This commit moves the mounting logic from `main.c` to frozen code using
`modules/_boot.py` and adds the formatting of a previously unformatted
partition if the mount fails.
Every available disk (in the newly added `DiskAccess.disks` tuple) will be
mounted on separate mount points (if they're formatted), and the 'storage'
flash partition (if any) will be mounted on /flash (and will be formatted
as LFS2 if necessary).
Also, `sys.path` will be updated with appropriate 'lib' subdirectories for
each mounted filesystem.
The current working directory will be changed to the last `DiskAccess.disk`
mounted, or to /flash if no disks were mounted.
Then `boot.py` and `main.py` will be executed from the current working
directory if they exist.
Thanks to @VynDragon for the logic in `zephyr/zephyr_storage.c`.

This commit adds `Sensor.attr_set()` and `Sensor.attr_get_*()` methods that
are necessary to set various sensor attributes if they haven't been set
statically in the device tree.
This is needed, for example, because the LSM6DS3TR-C sensor on the XIAO BLE
NRF52840 SENSE board will not work with `zsensor` because it doesn't have
any default configuration for sampling frequency.
Various `SENSOR_ATTR_*` constants from
`zephyr/incude/zephyr/drivers/sensor.h` have been added as `ATTR_*`
constants in the `zsensor` module.

This commit adds support for ADC peripherals in the Zephyr port.
As is typical for Zephyr, the ADC channel setup is done in the devicetree
(typically using an overlay). This code requires ADC channels to be listed
in the io-channels property of the zephyr,user root node.

Zephyr v3.7.0 added a new feature to allow getting devices by their
devicetree node labels. Use this feature in the MicroPython Zephyr port
to simplify constructing machine module objects, including Pin, SPI,
I2C, and UART. It's still possible to use the more verbose device names
(e.g., gpio@400ff040, i2c@40066000, spi@4002c000), but now we can also
use their devicetree node labels (e.g., gpiob, i2c0, spi0).
Node labels aren't standardized across all SoC families because they
generally try to follow their respective SoC hardware user manual naming
convention, however many boards define common labels for devices routed
to Arduino headers (e.g., arduino_i2c, arduino_serial, and arduino_spi).
That means I2C("arduino_i2c") will work on quite a few boards (>100 in
the main Zephyr tree).

Zephyr v3.2.0 deprecated the devicetree label property as a base
property, which had been used as the device name string for
device_get_binding(). The device name string is now the devicetree node
name appended with its unit-address. Update Zephyr port documentation
to reflect this change.

Anywhere a module is mentioned, use its "non-u" name for consistency.
The "import module" vs "import umodule" is something of a FAQ, and this
commit intends to help clear that up. As a first approximation MicroPython
is Python, and so imports should work the same as Python and use the same
name, to a first approximation. The u-version of a module is a detail that
can be learned later on, when the user wants to understand more and have
finer control over importing.
Existing Python code should just work, as much as it is possible to do that
within the constraints of embedded systems, and the MicroPython
documentation should match the idiomatic way to write Python code.
With universal weak links for modules (via MICROPY_MODULE_WEAK_LINKS) users
can consistently use "import foo" across all ports (with the exception of
the minimal ports). And the ability to override/extend via "foo.py"
continues to work well.
