This patch addresses the following issue:
In 2D mode when consecutive partial transfers occur, and the latter is
very short, will interfere with the completion mechanism of the first
transfer leading to uncompleted segments and unreported partial
transfers.
This simplifies the burst length in the response manager significantly
while not costing much extra resources in the burst memory.
This change will also enable other future improvements.

For consistent simulation behavior it is recommended to annotate all source
files with a timescale. Add it to those where it is currently missing.

Data mover/ src axis changes
Request rewind ID if TLAST received during non-last burst
Consume (ignore) descriptors until last segment received
Block descriptors towards destination until last segment received
Request generator changes
Rewind the burst ID if rewind request received
Consume (ignore) descriptors until last segment received
If TLAST happened on last segment replay next transfer (in progress or
completed) with the adjusted ID
Create completion requests for ignored segments
Response generator changes
Track requests
Complete segments which got ignored
Length of partial transfers are stored in a queue for SW reads.
The presence of partial transfer is indicated by a status bit.
The reporting can be enabled by a control bit.
The progress of any transfer can be followed by a debug register.
