[Mellanox] Add support of the nvidia-bluefield platform to generate-dump utility. (#3091)

- What I did
Add support of the nvidia-bluefield platform to generate-dump utility to collect platform-specific dumps on NVIDIA Bluefield DPU.

- How I did it
Extend platform-specific section of generate-dump utility

- How to verify it
Run "show techsupport" command to generate dump file. Verify that platform-dump directory exists in the created dump file.
