Bug 1896868: update InetBgDL.dll nsis plugin with a statically linked version r=nalexander,jcristau

This was built in a shippable win32 build on Try in https://treeherder.mozilla.org/jobs?repo=try&revision=0d8c6bee15ce9bc54a7749717033fa24e15ca0bf, which was based on 730319d762dc822e7319087f50a31ee268d4fb00, with updated versions of the patches from https://bugzilla.mozilla.org/show_bug.cgi?id=1771192 applied to it that statically link InetBgDL.dll.

From there, I sent it through adhoc-signing in https://github.com/mozilla-releng/adhoc-signing/pull/208.

The output from that (https://firefox-ci-tc.services.mozilla.com/tasks/EHnFhv77SO6K8D_ZS32fGQ) is what is included in this revision.
