refactor(boards): Adjust Zephyr board metadata file locations

Move the ZMK metadata files for upstream Zephyr boards to align with the
HWMv2 directory structure that uses the vendor ID for the parent
directory for a board directory.

fix: Don't enable ZMK Display by default for a few shields

By convention, avoid enabling ZMK Display by default on shields that may
be built with under-resourced controllers (e.g. nRF52833 based ones).

fix: Remove usage of renamed Kconfig from core coverage.

Avoid using WS2812_LED_STRIP, since that Kconfig was renamed/split into
SPI/GPIO/I2S symbols.

refactor(boards): Adjust XIAO RP2040 override names, bootloader support

Adjust the .conf/.overlay files to match the proper naming for the
XIAO rp2040 board. Also add the necessary Kconfig/DTS bits for
supporting bootloader using retained memory/boot mode retention.

fix(display): Adjust stack sizes for display usage.

Updated LVGL is bumping our stack size, so adjust the system work queue
and dedicated display queue stack sizes as needed to account for this.

feat(display): Add thread name to dedicated display queue.

When thread names are enabled, pass a name to the dedicated display
queue for better tracibility when using the thread analyzer.

docs(blog): Add Zephyr upgrade post

docs: Add bootloader integration page

Add a dedicated page to outline steps to set up bootloader integration
using the boot retention mechanism in newer Zephyr versions.

fix(display): port nice!view display code

* remove `lv_` prefix from old LVGL methods

doc: Update local setup docs to use `west packages pip`

Install Zephyr deps using the newer `west packages pip --install`.

Signed-off-by: Peter Johanson <peter@peterjohanson.com>

refactor(split): Adjust BT split code for newer Zephyr APIs.

refactor(boards): Adjust upstream RP2040 boards for boot mode retention

Add necessary DTS/Kconfig settings to upstream RP2040 boards so they can
use the ZMK bootloader functionality using the boot mode retention
infrastructure.

docs: Update Zephyr docs links to 4.1.0 version.

Update all links to the Zephyr docs to the 4.1.0 versions to match our
Zephyr version in use.

docs: Add a note about using CMake v3 for maximum compatibility.

Some optional modules, like libmetal, which is used on nRF5340,
specifically require CMake v3, so add a note in the native toolchain
setup about this.

feat(pointing): Handle INPUT_BTN_TOUCH codes for mouse buttons

Translate INPUT_BTN_TOUCH input codes into button 0 press/release for
HID layer.

chore(pointing): Clean up some warning messages.

Properly check return code from queue-ing messages, and fix up some type
warnings in our logging calls.

* Fix input event codes line numbers

fix(studio): Properly serialize GATT RPC indications.

fix(core): Set a system work queue stack size of 2048 by default

We use a fair amount of stack even without BLE or RP2040, so default to
2048 by default everywhere, and constrained platforms can lowes this if
they really need.

refactor(core): Move away from deprecated DIS Kconfig symbols

Use the correct Device Information Service Kconfig symbols for our model
number and manufacturer.

refactor: Move upstream Zephyr board overrides to extensions dirs

Newer Zephyr supports "board extensions" to formally do what we've added
in ourselves via some hacks, so move all our board overlay/config file
overrides for upstream Zephyr boards into that correct structure.

fix(boards): Add xiao_ble sd_partition label for nosd snippet compat

Upstream xiao_ble uses different naming convention for the partition
labels, so add an additional label for the SD range, so the existing
nrf52840-nosd snippet will still work with the board.

fix(core): Don't force CBPRINTF_NANO, for proper formatting.

The nano CBPRINTF implementation lacks some padded formatting needed to
ensure consistent formatting of BLE addresses, which we use to store
keys as strings in a few places, so use the complete CBPRINTF by default
now.

fix(boards): Remove some references to old nice_nano_v2 board ID.

The nice!nano board definition now properly uses versioning, so avoid
referring to it with old `nice_nano_v2` board ID.

fix(boards): Remove nano overlays for old nice_nano_v2 board ID.

With board versioning in place, we can remove the unused
`nice_nano_v2.overlay` files from shields.

feat(split): Runtime selection of split transport (#2886)
feat(split): Runtime selection of split transport

Allow building multiple split transports, and select an active
one based on the transport availability. Wired split availability
depends on additional `detect-gpios` which must be a GPIO pin
that goes active when a wired connection is present.

feat(split): Suspend/resume wired UART devices.

To better support runtime split support, suspend/resume the UART
as necessary to save power when not using the UART.

docs(split): Document adjusting nRF52 UART interrupt priorities

For wired split on nRF52, you may need to adjust the priority for UART
interrupts lower, to ensure the interrupts used for timing sensitive
BT operations can run when needed, so document this in our pinctrl docs.

refactor(split): Restore use of aync UART on nRF52.

With fixes for Zephyr UART driver, re-enable using async API on nRF52.

fix(split): Minor wired split fixes.

Various minor fixes for wired split to avoid spurious TX in half duplex,
etc.

fix: Unconditionally define HID payloads to avoid error.

Don't conditionally define HID indicator payload, to avoid compilation
errors.

docs(split): Expand on details of split transports.

Expand the split keyboard documentation with a more fleshed out section
on the available split trasnports, and what is and isn't supported by
each, including the runtime selection functionality.

Feature: Full-Duplex Wired Split (#2766)
refactor(split): Refactor split code for extension

Extract central/peripheral code to allow for plugging in alternate
transports, instead of tying all split logic to BT.

feat(split): Add full-duplex wired split support

* Depends on full-duplex hardware UART for communication.
* Supports all existing central commands/peripheral events, including
  sensors/inputs from peripherals.
* Only one wired split peripheral supported (for now)
* Relies on chosen `zmk,split-uart` referencing the UART device.

docs: Add wired split config docs.

Migrate split to its own dedicated config file, and add details
on wired split config.

fix: Properly override stack size on RP2040

SoC.
