CI: Fix broken CAS path for macOS analyze builds

With the switch to Xcode 26.5 the analyze command started to use the
built-in compilation cache (per the CMake preset) which breaks those
builds specifically as no writable CAS path is set for this workflow.

This change adds the same code used for the normal build workflow to
set a specific CAS path. Because the contents of that path are not
retained by a caching action, no actual caching for analyze builds takes
place.
