[vcpkg] Fix the build on VS2015 debug (#7637)
The VS2015 standard library requires, in debug mode, a comparison operator on `T × U` and `U × T` to also be a comparison operator on `T × T` and on `U × U`, and so in vcpkg::Install::install_package::intersection_compare, I've added two new `operator()` overloads which take those respectively, on VS2015. Also, `[nodiscard]` was added to somewhere in `vcpkg/base/strings.h`, which gives a warning in VS2015 -- thus, I added the `vcpkg/pragmas.h` include, since that fixes the warning.
