This PR fixes two bugs:

One in the metadata after GPU decompression, leading to more carry propagation done
Another in the conversion between Cpu and Gpu CompressedList


This change is Reviewable

For Signed and Unsigned DataKind, the degree was
incorrectly set, leading to unneeded carry propagations
Some counts where to copied from the correct
source to correct destination.

And a spurious truncation of a GLWE was done
