Detailed description

Supersedes #2456

Modernize testing.

The new unit testing is build around yaml files. They can be consumed by the C test engine (cstest) or any bindings easily.

Statistics

The new cstest logs technically two statistics. One by cmocka and one by cstest.
The reason is:

1. We might want to group tests in the future (by arch or file for example) so we need a global statistics.
2. Errors of incorrect yaml parsing are not tracked by cmocka.
3. Also, cmocka doesn't provide the detailed statistics to us. So we cannot print a nice summary at the end.

Changes

• New cstest C-implementation
• New py_cstest Python-implementation
• Moves almost all tests to yaml files.
• Old tests which can't be moved (because they are effectively integration tests) are kept.
• Add numerous test jobs in the workflow
• Adds several CMake test targets
• Add LoongArch Python bindings
• Several bug fixes discovered during testing.

Current test coverage of Auto-Sync <ARCH>Mapping.c files by running cstest test/:

file	coverage	covered
arch/LoongArch/LoongArchMapping.c	67.29%	144 / 214
arch/PowerPC/PPCMapping.c	72.78%	254 / 349
arch/AArch64/AArch64Mapping.c	60.47%	918 / 1518
arch/TriCore/TriCoreMapping.c	45.00%	45 / 100
arch/Alpha/AlphaMapping.c	86.08%	68 / 79
arch/ARM/ARMMapping.c	61.68%	792 / 1284
arch/HPPA/HPPAMapping.c	29.85%	20 / 67

After merge
