Donglin Peng 6b0c7c28f7 tracing: Pretty-print enum parameters in function arguments 
Currently, print_function_args() prints enum parameter values
in decimal format, reducing trace log readability.

Use BTF information to resolve enum parameters and print their
symbolic names (where available). This improves readability by
showing meaningful identifiers instead of raw numbers.

Before:
  mod_memcg_lruvec_state(lruvec=0xffff..., idx=5, val=320)

After:
  mod_memcg_lruvec_state(lruvec=0xffff..., idx=5 [NR_SLAB_RECLAIMABLE_B], val=320)
