vim-patch:9.2.0743: string macros silently accept a size of the wrong type (#40470)

Problem:  Several string and memory wrapper macros cast their size
          argument to size_t although the wrapped function's prototype
          already declares that parameter size_t; such casts silence the
          warning a compiler would otherwise give when a value of the
          wrong type, such as a pointer, is passed as the size.
Solution: Where the wrapped function's prototype already declares the
          parameter size_t, remove the cast so that a size argument of
          the wrong type can be reported at compile time (K.Takata,
          Shane Harper).

From gcc 14 on, -Wint-conversion is an error by default.

With gcc, passing a signed value where size_t is expected triggers
-Wsign-conversion, but the check is off by default and the build already
emits many such warnings.
