Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

Test of the sys_heap_aligned_alloc() API. This is separate from the
existing heap test because aligned_alloc() requires a kconfig to
enable it that can change the heap block header format and will impact
code coverage of the "small" block variant.
It's a fairly simple whitebox test that instantiates a heap and then
enumerates all possible alignments within it, with and without
pre-allocated data, to verify that the resulting memory is correctly
aligned and the heap stays consistent.
