Christian Blichmann 41e0ca0a68 CMake: Use min v3.13 and FetchContent
This updates the mininum required version of CMake to 3.13, which is
present in Debian Buster.

At the same time, move all of our dependency handling to use
`FetchContent_Declare()`, `FetchContent_Populate()` and
`FetchContent_MakeAvailable()`. Since the latter was ony introduced in
3.14, provide a simple "polyfill" implementation for that.

As an added benefit, the configure step for libffi and libunwind will
now not be re-run every time the `CMakeLists.txt` changes.

Other changes:
- Explicitly spell out that we're testing up to 3.22 in
  `cmake_minimum_version()`
- Rename `check_target()` to `sapi_check_target()` to avoid conflicts
  with Abseil.
