fix(nrLDPC_coding_interface): Move the encoding output to the TB

Since this branch aims to bring all the encoded segments packed and contiguous,
it doesn't make anymore sense to have one output array per segment.
Therefore this commit moves the output array to the TB instead of the segment and adapts its size.

TODO: Adapt the size of f where it is relevant.
