[Core] Unite half-duplex and full-duplex serial drivers (#13081)
* Unite half-duplex and full-duplex serial driver.

* Add full duplex operation mode to the interrupt based driver
* Delete DMA UART based full duplex driver
* The new driver targets #11930

* Fix freezes with failing transactions in half-duplex

* Increase default serial TX/RX buffer size to 128 bytes

* Correctly use bool instead of size_t

Extensible split data sync (#11930)
* Extensible split data sync capability through transactions.

- Split common transport has been split up between the transport layer
  and data layer.
- Split "transactions" model used, with convergence between I2C and
  serial data definitions.
- Slave matrix "generation count" is used to determine if the full slave
  matrix needs to be retrieved.
- Encoders get the same "generation count" treatment.
- All other blocks of data are synchronised when a change is detected.
- All transmissions have a globally-configurable deadline before a
  transmission is forced (`FORCED_SYNC_THROTTLE_MS`, default 100ms).
- Added atomicity for all core-synced data, preventing partial updates
- Added retries to AVR i2c_master's i2c_start, to minimise the number of
  failed transactions when interrupts are disabled on the slave due to
  atomicity checks.
- Some keyboards have had slight modifications made in order to ensure
  that they still build due to firmware size restrictions.

* Fixup LED_MATRIX compile.

* Parameterise ERROR_DISCONNECT_COUNT.
