[wasm] debug with modularized runtime(s)

[pavelsavara]

Context

After we modularize the runtime, the APIs like MONO or INTERNAL would not be on globalThis anymore.
Also, there would be possibility to instantiate multiple runtimes in the same web page.

I don't think that multiple runtimes on same page nor multiple debuggers running on same page in parallel are very likely scenarios. This PR is just neat way how to allow that possibility in the future, while solving the isolation that ES6 will bring.

Changes

• New globalThis.getDotnetRuntime method, which takes runtimeId, essentially index of the runtime on the page. It returns the DotNetPublicAPI object of the instance {MONO, BINDING, Module, RuntimeId, RuntimeBuildInfo }.
• Change the debugger to use the getDotnetRuntime() function when talking to the runtime on the page via CDP.
• Use getDotnetRuntime() in unit tests, with runtimeId is zero as there is only one runtime in tests.
• We add optional &runtimeId=0 to the initial URL which opens DebuggerProxy, so that MonoProxy could be created for specific runtime on the page.
• Moved mono_wasm_add_dbg_command_received, mono_wasm_debugger_log and mono_wasm_trace_logger out of C macro into typescript
• Introduced RuntimeBuildInfo: { ProductVersion, Configuration } into DotNetPublicAPI

Looks good, needs debugger expert approval though

[thaystg]

Looks good to me.
Debugger tests passing. Debug a Blazor app also working.
