This change forks the benchmarks for the null safety feature where there
now is a null safe version at benchmarks/Foo/dart and a legacy Dart 2
version at benchmarks/Foo/dart2. This change allows benchmarks to be
migrated per go/dart-nnbd-benchmark-migration.
Additionally this change pins the internal benchmarks which have been
moved into their own repository and is now versioned along with the Dart
SDK.
The dart2 implementation will be benchmarked instead of the null safe
dart implementation as of this change. The null safe dart implementation
will be used when null safe benchmarking is turned on.

The majority of UTF-8 decoding in Dart programs is done via the
utf8.decode() call. Therefore, our benchmark should do the same to
better reflect realistic use.

This is in preparation for upcoming optimizations to the UTF-8 decoding.
The data files are extracts from Wikipedia with markup stripped. They
cover 6 representative cases of typical input data:
- English text, only ASCII
- Danish text, mostly ASCII, only Latin-1
- Slovak text, mostly ASCII, not only Latin-1
- Russian text, max 2 bytes per character
- Nepali text, max 3 bytes per character
- Chinese text, full character range
Each of the languages are benchmarked with small (average 10 bytes),
medium (10 000 bytes) and large (10 000 000 bytes) inputs.
Only allowMalformed: false is benchmarked.
