Use SubtleCrypto API on browser DOM scenarios (#65966)

* Use SubtleCrypto API on browser DOM scenarios

* Add sync over async implementation

* Address misc feedback and make fixes

* Address pinvoke errors

* [Attempt] Correct execution of native digest API call at wasm layer

* [Fix up] Correct execution of native digest API call at wasm layer

* Update src/tests/BuildWasmApps/Wasm.Build.Tests/BuildTestBase.cs

* Address feedback and clean up

* Re-implement the crypto worker in ts

* Address feedback

* Revert "Re-implement the crypto worker in ts"

This reverts commit 6a743909605fb5b1194cae6bf571c2e6ff059409.

* * moved stuff around and renamed it
* initialization bit later

* Add code to handle errors in worker (particularly on init)

* Clean up

* Add crypto dll to wasm native project

* Add e2e test

* Adjust test to reflect lack of SharedArrayBuffer for Chrome in test harness

* Enable Chrome test and validate hashed value in tests

* fix merge to track assert being renamed to mono_assert
