This reverts commit cab69e7706.
Reason for revert: It was a temporary submit
Original change's description:
> [BUILD] - Initial CL to unfork the NNBD Dart SDK
> NOTE: This is a trial submit and will be reverted immediately.
>
> - 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
>
