This commit is being done so we can roll it into Flutter and run some device lab testing to see the effect this CL will have on Flutter. [BUILD] - Initial CL to unfork the NNBD Dart SDK - Flips the flag from --nnbd to --no-nnbd so that by default it builds the NNBD version - using the --no-nnbd flag results in the SDK being built in a directory which has the 'Legacy' suffix added to it (e.g: out/DebugX64Legacy) - the '--enable-experiment=non-nullable' flag still needs to be passed in during execution so that CFE runs in that mode. This is different from the 'null_safety' flag Change-Id: I83c813aee2a5b61ad876d8a7b0988705bb24c839 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/144082 Reviewed-by: Siva Annamalai <asiva@google.com>
