- Detect null safety when not specified before isolate
initialization
- for source files by having CFE parse the source file
for @dart annotations
- for kernel files by sniffing the kernel file for
compilation mode
- for appJIT files by sniffing the feature string
- for AOT snapshots by sniffing the feature string
- Remove workaround of returning null safety to false during
bootstrapping
- Add a new Dart C API call for detecting null safety
