Fixes https://ci.chromium.org/ui/p/dart/builders/ci.sandbox/pkg-win-release-arm64/3781.
With new split the steps are distributed roughly like this:
```
$ RBE=0 tools/build.py -mrelease -ax64 gen_snapshot
[982/982] LINK ./gen_snapshot
The build took 39.285 seconds
$ RBE=0 tools/build.py -mrelease -ax64 runtime/bin:dart runtime/bin:run_vm_tests
[1392/1392] LINK ./run_vm_tests
The build took 97.936 seconds
$ RBE=0 tools/build.py -mrelease -ax64 runtime
[1223/1223] ACTION //utils/kernel-service:frontend_server_aot_product(//build/toolchain/linux:clang_x64)
The build took 97.168 seconds
$ RBE=0 tools/build.py -mrelease -ax64 create_sdk ddc_stable_test
[402/402] COPY gen/dart2js_aot_product.dart.snapshot dart-sdk/bin/snapshots/dart2js_aot.dart.snapshot
The build took 100.373 seconds
```
Also add Ryan to the OWNERS_INFRA.
