Remove the unused SANITIZE_PTRS destructor poisoning blocks from AK
pointer wrappers. Also drop the stale Qt Creator configuration define
that referenced this old mode.
This allows us to get rid of the annoying Build/.../Lagom directory
and helps to deduplicate a bunch of logic while also drastically
simplifying everything.
The reason for this change is that CMake/vcpkg are unable to detect a
change to VCPKG_LIBRARY_LINKAGE. So when we switch to dynamic builds,
the switch would be non-functional, and every developer would have to
remove their Build and vcpkg cache directories manually. By changing
these directories, vcpkg is able to detect it must rebuild.
