[mono][aot] macOS: Permission issues with workloads

[radical]

Based off #53314 .

Steps to reproduce:

1. install dotnet preview 4 (https://dotnet.microsoft.com/download/dotnet/6.0), into a system location
2. install the workload packs with: dotnet workload install microsoft-net-sdk-blazorwebassembly-aot. You would need to run that as root
3. create a new blazor project with dotnet new blazorwasm
4. Add <RunAOTCompilation>true</RunAOTCompilation>, and <PackageReference Include="Microsoft.AspNetCore.SignalR.Protocols.MessagePack" Version="6.0.0-preview.4.21253.5" /> to the project
5. build with dotnet publish -c:release -p:RunAOTCompilation=true -bl

Fails with:

Problem 1. mono-aot-cross has execute permission only for the owner(root).

fixing the permission for that, and building again fails with:

Problem 2: emcc (and possibly other emscripten files) don't have the right permissions

This should probably help: dotnet/sdk#16894

[directhex]

It looks like parsing data/UnixFilePermissions.xml was added a week ago: dotnet/sdk@5305f48 which ties in with @akoeplinger's link

I'll look at adding that file to the blazor workload pack, probably based on the template from Android (dotnet/android#6010)
