ae857da chore(parsers): optimize ParseMmapProt

Refactor ParseMmapProt to use mmapProtArgs slice.

- Introduced mmapProtArgs slice for cleaner and more maintainable code.
- Replaced multiple if statements with a loop and string builder.
- Improved performance: reduced allocs/op from 17 to 15, and B/op from
  392 to 352.
- Execution time slightly improved from 1603 ns/op to 1536 ns/op
  (benchmark file used included).
- Reduced function size from 1534 to 677 bytes (55.8% less), what
  should improve locality and reduce cache misses.
