remove old bench & revert the frame-weight-template (#7362)

- remove old bench from cmd.py and left alias for backward compatibility
- reverted the frame-wight-template as the problem was that it umbrella
template wasn't picked correctly in the old benchmarks, in
frame-omni-bench it correctly identifies the dependencies and uses
correct template
