Clemens Hammacher 6be6ec0091 [wasm] Store WasmModule in shared_ptr during async compilation
We currently store the {WasmModule} (generated during decoding) in a
unique_ptr and pass ownership to the {WasmModuleObject} after
compilation.
I plan to move the {Managed<NativeModule>} from {WasmCompiledModule} to
{WasmModuleObject}, which will force us to create the
{WasmModuleObject} *before* compilation, so that the {CompilationState}
is available during compilation.

This CL prepares that refactoring by storing the {WasmModule} in a
{shared_ptr} in the {AsyncCompileJob}. Note that it will eventually be
stored in a {shared_ptr} in the {Managed} anyway.
