Add K_keep parameter to codec evaluation scripts

- Add K_keep=2048 to eval_ov_encoder_large_2kpatches_codec.sh
- Add K_keep=4096 to eval_ov_encoder_large_4kpatches_codec.sh
- Update common_codec.sh to accept and pass K_keep parameter
- Fix filename issue with common_codec.sh (removed special character)
