Opt an initial batch of files under samples, samples-dev,
utils, and runtime/tools/dartfuzz out of null safety in preparation
for switching the flag on by default.

Aart Bik f29e100f42 [dart/fuzzer] Generate DartFuzz API tables automatically 
Rationale:
Rather than manually constructing the API tables for DartFuzz,
this introduces a utility to generate API tables based on
the analyzer traversal of common libraries. The utility
recognizes DartTypes that are currently understood by DartFuzz
and constructs the tables organized by return type.

TBD:
DartFuzz's type system is rather simple; as this improves,
more and more methods will be accepted by the utility,
thereby increasing fuzzing coverage of our libraries.
