CLEANUP: cli: rename dynamic error printing state

Rename CLI_ST_PRINT_FREE to CLI_ST_PRINT_DYNERR.

Most notably, this highlights that this is reserved to error printing.

This is done to ensure consistency between CLI_ST_PRINT/CLI_ST_PRINT_DYN
and CLI_ST_PRINT_ERR/CLI_ST_PRINT_DYNERR. The name is also consistent
with the function cli_dynerr() which activates it.
