Update CMake tool version to 3.16.2 on Windows, Linux, MacOS

[mbeutel]

This PR updates the version of the CMake instance used by Vcpkg to build packages.

• What does your PR fix? Libraries that require CMake 3.15 or CMake 3.16 cannot currently be built with Vcpkg unless a custom CMake version is supplied because Vcpkg pulls an outdated version of CMake.

• Which triplets are supported/not supported? Have you updated the CI baseline? does not apply

• Does your PR follow the maintainer guide? yes

Isn't the vcpkg cmake version supposed to be the same as the one that ships with the latest Visual Studio release?

Otherwise, why 3.16.2 instead of 3.16.0? Those are mostly bugfixes that don't affect vcpkg targets.

@qis I didn't find anything about CMake version policy in the maintainer guide. I chose CMake 3.16.2 because it's the latest and greatest, and because I'd really like to rely on some new features (MSVC_RUNTIME_LIBRARY semantics in CMake 3.15, precompiled headers in 3.16) in my libraries.

I'm surprised by the number of port breakages though.

@mbeutel to be honest most if not all the failures look spurious.

What does that mean? Browsing through the build logs, I couldn't spot anything that seemed directly related to CMake; but what else would have caused these errors? One of these packages already failed in the commit on which I had branched, but several others apparently were fine.

Anyway, I just rebased this PR on top of current master, so perhaps some of the failures will now go away.

[mbeutel]

And the MacOS pipeline already failed. That indeed looks spurious :(

@mbeutel OSX build failures will resolved in #9726.

@mbeutel thanks for being a sport and fixing things that have nothing to do with your change.

[mbeutel]

@cbezault not sure which fixes you are referring to? Unfortunately I didn't have the time to work on the fallout yet. I plan to do so because not having CMake 3.16 in Vcpkg is holding me back, but I don't know when I'll have time for it.

@mbeutel I opened a new PR #10767 to update cmake to a newer version.
