Use llvm_canonicalize_cmake_booleans for LLVM_LIBXML2_ENABLED [llvm]

r291284 added a nice mechanism to consistently pass CMake on/off toggles to
lit. This change uses it for LLVM_LIBXML2_ENABLED too (which was added around
the same time and doesn't use the new system yet).

Also alphabetically sort the list passed to llvm_canonicalize_cmake_booleans()
in llvm/test/CMakeLists.txt.

No intended behavior change.
