libc: implement `fopen()` #66939

This was originally added as a ticket under POSIX, but fopen() is not a POSIX function. It is from C89.

https://en.cppreference.com/w/c/io/fopen

The expectation from the POSIX API is that this function is implemented as part of whatever C library is in use.

Implementing this should fix #66132

Hi @cfriedt , I would like to implement this as well (and bunch of other posix methods like fclose, foef, ferror, and modifying fwrite) since I'm already working on implementing the fread. Thanks!
