Detailed description

Add ASAN builds

It does a few things

• Fixes the CAPSTONE_DIET build. Though it is not tested, since we cannot do it with the current test design, which relies on printing everything.
• Fix a lot of mem leaks,
• Fix the build of cstest via CMakeLists.txt. This allows now also to enable ASAN for the cstest. Also it is much easier to build cstest now.
• Fixes cstest-report.py to work also when cstest is installed and in PATH.
• Make run_invalid_cstool.sh more verbose to help spotting possible ASAN errors.
• Add and fix tests/cs_details/issue.cs to the CI.

Test plan

CI green (or, if everything fails horribly, mark it optoinal for now)

Closing issues

closes #2368

I remove the DIET changes again. Build is still fixed.
They are too complicated to fix for now and not testable. Because we can only test the details and decoding by printing it first, all the test cases of us fail.
So I think if we fix it it should be done once in a separated PR.
Also we can reduce the binary size even more.

Cool! In the future we also should enable UBSAN, I know there are many potential places that can trigger it. But that's a story for another PR...

@kabeor please take a look and lets merge this quickly, so new PRs will not introduce ASAN warnings.
