boards/arm/stm32: add nucleo-f412zg ostest and coremark configs.

Add dedicated ostest and coremark defconfigs for nucleo-f412zg.
The ostest config keeps the existing NSH-oriented board setup and
adds the runtime self-test application, while the coremark config
boots directly into the benchmark with an -O3 build profile.

Both configurations were verified with GNU Make and CMake/Ninja
using Arm GNU Toolchain 15.2.Rel1 on macOS arm64.
