Andreas Haas 115b866443 Reland "[wasm] Initialize compilation progress before compilation units" 
WasmFeatures::FromIsolate() was called without a HandleScope in the
original CL. This was fixed by using the WasmFeatures from the
NativeModule instead of calling WasmFeatures::FromIsolate.

Original message:

Initializing the compilation progress first, and making it an explicit
step, allows us to share the wrapper compilation code between async
compilation and streaming compilation. In the future it will also allow
us to initialize compilation units based on the compilation progress,
which will allow us to share more code between async compilation and
deserialization.
