[Fortran] Replace archaic intrinsic functions

[RRiva]

Over time, several intrinsic functions have been labeled archaic. See here for the complete list. They should be replaced by their modern equivalent. For example: dsin works for real, while csin and zsin for complex of different kind. They should be replaced by sin, which works for all cases.

Hi @RRiva,

Thank you once again for your continued contributions to improving the Open Catalog!

We didn’t have a specific check idea on our radar for this suggestion, but it certainly aligns with the Fortran modernization efforts. From what you’ve mentioned, it sounds like using these archaic functions doesn’t necessarily cause compilation failures (e.g., dsin and csin are in the F77 standard), but they could complicate maintenance, especially when refactoring code and changing data types.

As with your previous suggestions, if you're interested, feel free to open a PR proposing an entry for this check in the Open Catalog, following the tips shared in #36. Naturally, if you'd prefer, just let us know and we’ll be happy to take care of it :)
