curl_setup_once: drop `E*` macro redefines unused (with winsock2)

These were not used in curl sources at all.

Except `EDQUOT` which was used after `mkdir()` in `src/tool_dirhie.c`
for error display. It should not be redefined to a winsock2 error.
This makes the "exceeded your quota" error correctly appear on Windows,
if detected, after operations that create directories.

After this patch there remain 14 `E*` macro redefines on Windows,
down from 40 before this patch.

Bug: https://github.com/curl/curl/pull/16553#issuecomment-2704679377
Ref: #16612
Ref: #16605
Closes #16615
