Updates Cranelift Codegen dependence to 0.44

In trying to build the lightbeam feature in wasmtime there are
compile errors mostly related to outdated or missing trait
definitions. This patch moves the current cranelift codegen
dependence to 0.44 in support of that, though other changes
are still needed in wasmtime to get the feature to build.
