[202205][generate_dump]: Enhance show techsupport for cisco-8000 platform (#2533)

What I did
Added cisco-8000 specific platform information to "show techsupport" tarfile

How I did it
Added collect_cisco_8000 function to scripts/generate_dump which filters out the wanted files from /usr/share/sonic/device/${platform} and saves them in the techsupport tarfile under sai subdirectory

How to verify it
Run "show techsupport" and grep sai in the generated techsupport tarfile
