tracing/probes: Refactor parse_probe_arg()

Decompose parse_probe_arg() by extracting register, memory/symbol,
dereference, immediate, and default BTF/CPU parsing handlers into
dedicated static helper functions (parse_probe_arg_register,
parse_probe_arg_mem_symbol, parse_probe_arg_deref, parse_probe_arg_imm,
and parse_probe_arg_default). This modularizes the recursive argument
parser and improves readability.
