Bug description:Windows binaries comes by default with libidn instead of libidn2

Description:
------------
WHAT I DID:

I installed PHP8 on my Windows machine using binaries from
https://windows.php.net/download

WHAT I WANTED TO HAPPEN:

I wanted to use the cURL extension to query an IDN hostname.

WHAT ACTUALLY HAPPENED:

I realized cURL was using the old IDNA2003 protocol instead of the new
one: IDN2008 because the German letter "ß" was translated to "ss" in
the a-label queried. I check the curl_version() and I found the cause:
on Windows, PHP8 seems to be bundled with libidn instead of libidn2.
Please ensure the cURL extension is compiled with libidn2 instead of
libidn to generate the Windows binaries.

Test script:
---------------
php > var_dump(curl_version());
php shell code:1:
array(16) {
  [...]
  'version' =>
  string(6) "7.76.1"
  [...]
  'libidn' =>
  string(0) ""
  [...]
}
