Add support for building WASM variants alongside single-threaded to the build system

[directhex]

This is a first cut at allowing single thread, multi thread, and perftrace wasm builds to all happen as a single "thing"

• Add mono.wasmvariants subset to build variants
• Add variants to WASM package, or their own packages, TBD
• Add YAML to actually build this in CI

[directhex]

Right now, this is dumping the runtime variants in artifacts/bin/mono/Browser.Wasm.Release/wasm/{multithread,perftrace} and the native parts in artifacts/bin/native/net7.0-Browser-Release-wasm/wasm/{multithread,perftrace}

[directhex]

One issue(?) right now is you can't build the mono.wasmvariants subset without first building mono and libs

Without libs:

/home/directhex/Projects/runtime/eng/liveBuilds.targets(125,5): error : The 'libs' subset must be built before building this project. Missing artifacts: /home/directhex/Projects/runtime/artifacts/bin/microsoft.netcore.app.ref/ref/net7.0/. Configuration: 'Release'. To use a different configuration, specify the 'LibrariesConfiguration' property. [/home/directhex/Projects/runtime/src/mono/wasm/wasm.proj]

Without mono:

@steveisok I've eventually got this running with some very bad yaml. I tried parameterizing on runtimeVariant, but couldn't find a way to use the parameter in nameSuffix (which must be unique) without error. Moving from the old properties to the common MonoWasmBuildVariant property should make future parameterization easier.

I'm ok with a follow up to make things better.
