Fix sanitizer builds (#1579)

Browse Source 
Besides, remove unused ASAN_OPTIONS from github workflows.

Further, activate sanitizers for C++23 workflows, at the places
where we also activated -O3 optimization. Not activating everywhere
for CI efficiency reasons for now.

Note that the sanitizers are activated on clang C++23 workflows
only, since there is a remaining issue with GCC in delegate_cpp11.
