Subject: [PATCH 1/2] Reintroduce cmake_policy for CMake < 3.12

CMake warnings may be raised at least with CMake 3.10 and CMake 3.11.

Quoting Blzut3 from #3824:

> Yeah the point of using a range is so that you can keep the minimum
> low while having all the new policies set to NEW automatically. I
> suppose you're correct that 3.10 and 3.11 would raise a warning on
> that though.

Partially reverts commit d6ec9cc. I am aware this commit does not
address the cmake_minimum_required version in src/core, but neither did
the original commit this one is reverting.

Subject: [PATCH 2/2] core: Bump minimum CMake version to 3.5

AUTOUIC was introduced in CMake 3.0. The previous minimum required
version 2.8.12 is too old and probably wouldn't work.

At this time I'm not immediately sure what requires CMake 3.5, but the
other CMake files and recent commits are defining that as our minimum.

See: #3824
Fixup: d6ec9cc

Subject: [PATCH 3/3] core: Suppress CMake CMP0028 warnings (again)

For some reason, I assumed I didn't need to reintroduce CMP0028 for
CMake versions < 3.12. I believe I misread the documentation, although I
was aware of this policy being located lower in this file.

Partially reverts commit d6ec9cc.
