[CMake] Run libFuzzer tests with check-all.

[kcc]

LGTM
Please watch the bots -- I can imagine it can fail in lots of ways.

This commit broke AArch64 bots, a bugzilla entry was created to track the issue:

https://bugs.llvm.org/show_bug.cgi?id=38034

Sorry but I need to revert it

[george.karpenkov]

Do you think you can instead disable three problematic tests on AARCH64 and revert the revert?
That seems like a more local solution.

[yroux]

Sure, I'll do it today.
