[vcpkg baseline][poppler] Fix issue with using libcurl. (#15491)

* [poppler] Fix issue with using libcurl.

* [curl] Ensure CMake policy is set for the libcurl config file.

Otherwise, ports using old (eg pre-2.8) CMake minimums might fail when
they import the package.

* [poppler] Add curl feature to test curl vcpkg-cmake-wrapper.
