  -----------
  [ASan] Change strdup interceptor to allow null input on Windows (#122803)

[These are the MS
Docs](https://learn.microsoft.com/en-us/cpp/c-runtime-library/reference/strdup-wcsdup-mbsdup?view=msvc-170)
regarding `strdup`, but they don't explicitly mention this. The SAL
annotations on `strdup` do, though, with the input parameter being
marked `_In_opt_z_`.
