[FHI72] [xran F] Handle fragmented (un)compressed packets

In both E and F, the radio-transport fragmentation is not supported, and
all the "fragmented" (not seen as fragments in the xran, only as
sections) packets contain "E-bit" equal to 1. Per spec, the value 1 for
"E-bit" signifies the last fragment of one symbol. For more info, please
see "ecpriSeqid" section in the spec.

In E:

- nRBStart and nRBSize is updated according to the sent/received packet;
- max sections = 1;
- when a packet is fragmented, the xran uses memcpy(pos, iq_data_start,
  size) function, and nothing is stored in start_prbu , num_prbu ,...

In F:

- nRBStart and nRBSize is only used for C-plane messages;
- nPrbElm represents the number of sections for DL only;
- based on the nPrbElm, each section contains UP_nRBStart and UP_nRBSize
  parameters which represent the start and number of PRBs in one section
  or one fragment;
- when a packet is fragmented, the xran uses nSecDesc and sec_desc to
  extract the packet section content, and the data is stored in
  start_prbu , num_prbu ,...

Previous work on the fragmentation in F:

- #884
- !3394 - only increases the XRAN_MAX_FRAGMENT from 4 to 6, since it was
  only tested with BFP 8, but not end-to-end unfortunately. But this MR
  fixes all the issues.

Tested with VVDN RU, 2x2, 16 bits, 100MHz, 30kHz, MTU <= 9216 B, and
Quectel UE RM520N-GL Revision: RM520NGLAAR03A03M4G.
