Remove debug dump import by default (sonic-net#3715)

- What I did
Remove debug dump import by default, Starting 202411, debug dump started to import libdashapi to parse DASH objects.

Keeping this in default import path is causing CLI execution time to increase.

- How I did it
Make the import on-demand

- How to verify it
UT and verified on the image
