chore: New module/serial API (#3055)

* WiP: new module interface

* WiP: softserial timer DMA

* WiP: setup() and send() in one step

and remove methods specific to internal or external module

* fixes and extra port config

* horus targets

* module ports have moved

* T8 support (only internal module)

* fix nv14

* stupid GCC....

* disable BT

* remove nv14 telem driver

* remove old aux serial driver

* Move module buffers out of pulses.h

* Soft serial fixes and PXX1 support

* Fixed PPM module output

* Fixed CLI

* compilation fixes

* Ported bluetooth and flysky gimbal to new serial driver

* Re-enable soft-serial RX

* fixes and cleanup

* nv14 fixes

* Fix flysky gimbals

* Ghost module

* 16 bytes of RAM

* Remove getByte from module API

* Ghost cleanup

* fix: _half_duplex_input() must be called after usart init

* WiP

* more cleanup

* Remove board specific settings from PXX1 / PXX2 drivers

* A bit of PXX2 header cleanup

* Add support for OVER8 and ONEBIT

* Add some support for inverters (NV14 / EL18)

* Support NV14 power fixes in generic board

* Fix polarity handling

* Fix RX DMA

* Fix mixer not running

* Add soft-serial polarity control

* Quick fix for telemetry polling while module port is changed

* Fix bootloader DEBUG

* Fix MPM telemetry

* Fix pulse start

* DSM2 soft-serial fallback

* DSMP async module restart

* Fix CRSF LUA upstream

* Remove global variable telemetryProtocol

* Use HAL/LL constants

* Fix various issue with AFHDS3 and NV14/EL18 internal module

* Fixed S.PORT unit tests

* fix: update widx after writing at current index

* fix: init error condition

* Fix: possible infinite loop in _find_port()

* Add support for bidir S.PORT init

* Add support for "getLastByte" in HW serial driver

* PXX1: Add support for S.PORT based on IDLE callback

* Fix rebase error

* Fix softserial _rx_fifo_push()

* Add softserial support for waitForTxCompleted()

* Fix MPM flashing (internal / external)

* Fixed external MPM

* Activate RX DMA on internal module

Seems to work with serial passthrough without issues, at least on the L3R PRO.

* Fix softserial DMA on stdlcd F4 targets

* Add softserial support for 32bit timers (mostly TIM2)

* More precise soft-serial

* Fix MPM update using inverters & HW uart

* Raise S.PORT DMA/USART IRQ prio to achieve faster switching to input

* Remove useless delays

* Fix flashing external ELRS module

* Added a retry mechanism for FrSky S.PORT update

* Remove useless enableRx()

* External FrSky modules are all flashed via S.PORT

* Remove power management unit update

This was only used on the first batch of X-lite.
