Add a switch to compile dotnet.js as ES6 module (#41964)

* Add a switch to compile dotnet.js as ES6 module

With `./build.sh -os Browser /p:WasmEnableES6=True`, we can now compile
`dotnet.js` as an ES6 module, which can be easily be loaded in
environments like Deno. e.g.:

```js
// myApp.js

import jsdom from "https://dev.jspm.io/jsdom";
window.document = new jsdom.JSDOM(null, {url:'http://localhost'}).window.document;

const dotnetModule = await import('./artifacts//bin/native/net5.0-Browser-Debug-wasm/dotnet.js');
// this is needed since we cannot pass scriptDirectory to upstream module (yet: https://github.com/emscripten-core/emscripten/pull/12120)
const bytes = Deno.readFileSync('./artifacts//bin/native/net5.0-Browser-Debug-wasm/dotnet.wasm', 'utf8');
const dotnet = await dotnetModule.default({wasmBinary: bytes}); // currently it calls run() on load

// dotnet.run(); // we can _additionally_ invoke run() on demand
```

Also waiting on Deno PR to merge with utf-16le suppot, workaround is:
```sh
$ ./build.sh -os Browser /p:WasmEnableES6=True
$ sed -i '' 's/utf-16le/utf8/' artifacts/bin/native/net5.0-Browser-Debug-wasm/dotnet.js
```
and then
```sh
$ deno run --allow-read myApp.js
```

* Set default value to False explicitly

* Use lower-case false for check

CoreCLR already handles `-DCLR_CMAKE_USE_SYSTEM_LIBUNWIND`, so no
changes are needed there.

The libraries build doesn't care about this cmake varibale, but cmake
itself fails if the variable is not used:

    EXEC : CMake error : [runtime/src/libraries/Native/build-native.proj]
        Manually-specified variables were not used by the project:

          CLR_CMAKE_USE_SYSTEM_LIBUNWIND

So libraries just needs to check and ignore this variable.

The singlefilehost needs to link against libunwind too. Otherwise the
linker fails to resolve symbols, making the build fail:

Fix to allow entering cooperative GC mode when the thread is in a forbid-suspend-for-debugger region (#42587)

- Followup to https://github.com/dotnet/runtime/pull/40060
- In short timing windows if a thread is placed in a pending-suspend-for-debugger state while in a forbid-suspend-for-debugger region, from the above PR it would not suspend for the debugger but it was missed that it can also get stuck in a perpetual spin-wait while entering cooperative GC mode. This causes the thread to not suspend for the debugger (VS times out after waiting) and the thread can only progress by unmarking it for debugger suspension.
- Fixed to break the spin-wait by checking whether the thread is in the forbid region
