mi_is_redirected method not found

[ovaar]

version: mimalloc/1.8.9
os: Windows

After the completion of #869, see aa88173#diff-4eea39c9329dca2c31253a2770771a90ad6d20bb76241d71cb78d68a9291d337L521, the function implementation of mi_is_redirected was removed.

Though the function is still listed in mimalloc.h, resulting in a link error. I tried patching it using the patch as described below, without luck resulting in a runtime error 0xC0000139: Entry Point Not Found.

This part was on me and is not an issue with mimalloc

Thanks so much for spotting this! Should be fixed now.
