Add missing workload references to Musl native EMSDK

[directhex]

Should be the missing fix for dotnet/sdk#32327 though likely these changes need to flow though to updated runtime (and maybe SDK) builds.

@directhex we need to backport this right?

It's a wider decision as to whether we want to backport the multiple related changes to enable support for building WASM/WASI with Alpine, since it's bringing two whole-ass new RIDs online (and switching the build OS for one of the pieces of EMSDK for all Linux platforms from Ubuntu to Mariner). @baronfel was exploring getting approval.

Ah ok, I only skimmed dotnet/sdk#32327 and didn't see that this is a musl-only issue.

[directhex]

It's an intersection of issues causing Musl to pull in the non-Musl emsdk/mono-aot-cross (which is normal given the RID graph). Native Musl packages for the required parts missed the no-chance-set-in-stone deadline for 8.0, and as you can see from this issue, some bugs weren't properly discovered and fixed until this week.
