This commit disables the "minimum required newlib heap size" check for
the newlib thread safety tests since they do not make use of any newlib
functions that require large heap.

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

This commit adds the tests for the newlib retargetable locking
interface, as well as the tests for the internal lock functions that
are supposed to internally invoke the retargetable locking interface.
All of these tests must pass when the toolchain newlib is compiled with
the `retargetable-locking` and `multithread` options, which are
required to ensure that the newlib is thread-safe, enabled. If the
toolchain newlib is compiled with either of these options disabled,
this test will fail.
This commit also adds the userspace testcases to ensure that the newlib
is thread-safe in the user mode.

This commit adds the `static` keyword to the test functions that are
not intended to be globally available.

This commit adds a new test to verify the thread safety of the C
standard functions provided by newlib.
Only the memory management functions (malloc and free) are tested at
this time; this test will be further extended in the future, to verify
the thread safety and re-entrancy of all supported newlib functions.
