We had a slightly older version of it for UWP, as the wincrypt API isn't allowed there.
We removed this with UWP in #81416, but since this was enabled inconditionally before,
this actually changed behavior for Windows compared to Godot 4.1 and earlier.
This change is also needed to properly supported Windows Store.
(cherry picked from commit b9d008de3d)
Keep applying the windows entropy patch (UWP support).
Remove no longer needed padlock patch.
Update thirdparty README to reflect changes, and new source inclusion
criteria.
The comment mentioned a conflict with libwebsockets, but we actually
still get this conflict even now that we don't use libwebsockets.
Not sure what component is clashing but we should basically just keep
this patch.
Follow-up to #36823.
