refactor(core): Adjust our approach for upstream Zephyr boards
Move to using proper HWMv2 board extensions
https://docs.zephyrproject.org/4.1.0/hardware/porting/board_porting.html#board-extensions
for extending upstream Zephyr boards for use with ZMK. With this change,
using upstream Zephyr board IDs directly, e.g. `seeeduino_xiao` will be
stock versions as found upstream. To use a board variant that is tuned
for ZMK use, use the `zmk` variant, e.g. `seeeduino_xiao//zmk` which is
shorthand for `seeeduino_xiao/samd21g18a/zmk`.
refactor(boards): Move to ZMK specific variants for the nRFMicro board
For consistency, adjust the nRFMicro board definition to offer a
"vanilla" Zephyr board, and then ZMK variants, e.g.
`nrfmicro/nrf52840/zmk`.
refactor(boards): Move to ZMK specific variant for the bluemicro840 board
For consistency, adjust the bluemicro840 board definition to offer a
"vanilla" Zephyr board, and then ZMK variant, e.g. `bluemicro840//zmk`.
refactor(boards): Make tofu65 to ZMK variant by default
Make the standard Tofu65 board ID be `tofu65/rp2040/zmk` or
`tofu65//zmk` by shorthand.
refactor(boards): Move BDN9 to ZMK variant by default
Make the standard BDN9 board ID be `bdn9/stm32f072xb/zmk` or
`bdn9//zmk` by shorthand.
refactor(boards): Move Puchi BLE to ZMK variant by default
Make the standard Puchi BLE board ID be `puchi_ble/nrf52840/zmk` or
`puchi_ble//zmk` by shorthand.
refactor(boards): Move Adv360 Pro to ZMK variant by default
Make the standard Adv360 Pro board ID be `adv360pro_left/nrf52840/zmk` or
`adv360pro_left//zmk` by shorthand and for right as well.
refactor(boards): Move nRF52840 M2 to ZMK variant by default
Make the standard nRF52840 M2 board ID be `nrf52840_m2/nrf52840/zmk` or
`nrf52840_m2//zmk` by shorthand.
refactor(boards): Move Pillbug to ZMK variant by default
Make the standard Pillbug board ID be `pillbug/nrf52840/zmk` or
`pillbug//zmk` by shorthand.
refactor(boards): Move s40nc to ZMK variant by default
Make the standard s40nc board ID be `s40nc/nrf52840/zmk` or
`s40nc//zmk` by shorthand.
refactor(boards): Move nice!60 to ZMK variant by default
Make the standard nice!60 board ID be `nice60/nrf52840/zmk` or
`nice60//zmk` by shorthand.
refactor(boards): Move planck to ZMK variant by default
Make the standard planck board ID be `planck/stm32f303xc/zmk` or
`planck//zmk` by shorthand.
refactor(boards): Move preonic to ZMK variant by default
Make the standard preonic board ID be `preonic/stm32f303xc/zmk` or
`preonic//zmk` by shorthand.
refactor(boards): Move ferris to ZMK variant by default
Make the standard ferris board ID be `ferris/stm32f072xb/zmk` or
`ferris//zmk` by shorthand.
refactor(boards): Move Proton-C to ZMK variant by default
Make the standard Proton-C board ID be `proton_c/stm32f303xc/zmk` or
`proton_c//zmk` by shorthand.
refactor(boards): Move Corneish Zen to ZMK variant by default
Make the standard Corneish Zen board ID be `corneish_zen_left/nrf52840/zmk` or
`corneish_zen_left//zmk` by shorthand and for right as well.
refactor(boards): Move nice!nano to ZMK variant by default
Make the standard nice!nano board ID be `nice_nano/nrf52840/zmk` or
`nice_nano//zmk` by shorthand.
refactor(boards): Move mikoto to ZMK variant by default
Make the standard mikoto board ID be `mikoto/nrf52840/zmk` or
`mikoto//zmk` by shorthand.
refactor(boards): Move Polarity Works boards to ZMK variants
Make the standard Polarity Works board IDs be `zmk` variants.
doc: Update docs/blog post to reference ZMK variants
* Update Zephyr 4.1 blog post to mention ZMK variants
* Add note to hardware support page about variants
docs: Fix up shield board overlays for new board IDs
Adjust our documentation to properly use the correct qualified board
overlay file names that match our new board conventions.
* Enhance the BLE test runner to build additional peripheral builds
when detecting peripheral*.overlay files in the test.
* Add basic and multiple-peripheral tests to exercise the testing
support
* Add test for triggering local behaviors on split peripherals.
fix(ble): Fix building split code w/o settings
* Properly exclude storing peripheral addresses to settings when
settings support isn't turned on.
* Add security related tests to verify behavior when trying to read
a GATT characteristic from our peripheral with and without client
auto security request/retry.
