DXC seems to be building inocrrectly with GCC-13 and later, which is causing our pre-merge testing on 24.04 to fail. This will take some time to sort out, so in the meantime I'm reverting to 22.04 on our pipelines.

GCC 13 (e.g. 13.3.0 shipped with Ubuntu 24.04) has a known miscompilation bug in -funswitch-loops (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109934) that causes widespread test failures when building DXC at -O3. Disable -funswitch-loops for GCC 13, and update the CI pipeline from Ubuntu-22.04 to Ubuntu-24.04 (which ships GCC 13 as default), removing the workaround from microsoft#7365.
