Move the pieces of the radio TX path that don't need FreeRTOS or NVS out of
Somfy.cpp and Web.cpp so they build in the native test env: the TX job and
event types and job encoding (TxBuffer), the queue rules (TxQueuePolicy.h),
a shade's pending radio jobs (ShadeTxState), the next rolling code
(RollingCode.h) and the web command queue types (WebCommand.h).

The frame was popped before queueTx(), so whenever the radio queue was busy
it was lost. Peek it instead, only remove it once it is queued (or TX is
suspended), and don't try while the queue has no room. The repeater buffer
moves to TxBuffer.h/.cpp so it can be unit tested.
