Add a generic function for tx write out of order (timestamps not increasing)

Add an API to allow out-of-order writes to a radio interface, unlike the
current interface.

this function is called in UE in this commit, even if the tx might
still be in order.

Later, i plan to improve UE pulti-threading, that will lead to out of
order tx.  also, the gNB will benefit of this new function to replace
several specific pieces of code that reorder tx with over complex and
slow systems
