[wasm] MT browser-bench crash

[radekdoulik]

I was trying to measure wasm/MT perf recently. The browser-bench is crashing for me, during the app start measurements, in this place:

AppStart, Reach managed count: 29, per call: 170.79310344827587ms, total: 4.953s
AppStart, Reach managed count: 31, per call: 178.83870967741936ms, total: 5.544s
dotnet.native.js:4738 Uncaught TypeError: Failed to execute 'getRandomValues' on 'Crypto': The provided ArrayBufferView value must not be shared.
