Jens Johansen a9469269d7 [kernel] BinaryReader takes Uint8List, not List<int>

In AOT this makes reading faster:

Output from `out/ReleaseX64/dart pkg/front_end/tool/benchmarker.dart --iterations=10 --snapshot=pkg/front_end/test/kernel_binary_bench.aot.1 --snapshot=pkg/front_end/test/kernel_binary_bench.aot.2 --arguments="--warmups=10" --arguments="--iterations=5" --arguments="AstFromBinaryEager" --arguments="out/ReleaseX64/vm_platform_strong.dill"`:

Stats running manually (run as e.g. `out/ReleaseX64/dart-sdk/bin/dartaotruntime pkg/front_end/test/kernel_binary_bench.aot.1 --warmups=10 --iterations=5 AstFromBinaryEager out/ReleaseX64/vm_platform_strong.dill`):

```

AstFromBinaryEagerWarmup: -8.33675% +/- 2.62433%
AstFromBinaryEager: -10.3432% +/- 3.68375%
```

I don't expect there to be much of a change (if any) in JIT as the actual type was in practise always Uint8List anyway.

TEST=Existing tests.
