With newer clang and gcc versions (observed on clang-17.0.6 as well as gcc 12/13), asan is throwing stack-use-after-return during OSD startup related to usage of seastar::async, which relies on swapcontext internally. seastar/src/core/thread.cc supports asan's hooks, but only if SEASTAR_HAVE_ASAN_FIBER_SUPPORT is set. seastar's CMakeList.txt sets it based on Sanitizers_FIBER_SUPPORT, which probably should be set by the module at src/seastar/cmake/FindSanitizers.cmake, but that module doesn't seem to be actually invoked anywhere. Ceph's version of that module (cmake/modules/FindSanitizers.cmake) does not set Sanitizers_FIBER_SUPPORT. This commit adds that check as well as the related code snippet.
