Pete Johanson 147c340c6e 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

Move the system work queue stack size override on RP2040 ouf of
a `ZMK_BLE` conditional so it is properly applied generally for that
SoC.
