net: do not call Windows TransmitFile for large files

TransmitFile does not allow for number of bytes that can be
transmitted to be larger than 2147483646. See

https://docs.microsoft.com/en-us/windows/win32/api/mswsock/nf-mswsock-transmitfile

for details. So adjust sendFile accordingly.

No test added, because this would require creating large file
(more than 2GB file).

Fixes #33193.
