Add support for `dotnet publish --no-build`

*Migrated from: https://github.com/dotnet/sdk/issues/35705*

---

Using a very specific combination of dotnet CLI arguments and msbuild properties, .NET 7 (and lower?) would allow you to run a publish with `--no-build`. This no longer works when I upgrade my solution to use .NET 8, but only specifically breaks for Xamarin projects (i.e. has `net8.0-macos` target framework).

### Steps to Reproduce

1. Clone the following repo and checkout the `dotnet8/dotnet8` branch: https://github.com/jwosty/DotnetMacosNoBuildBug/tree/dotnet8/dotnet8
2. Run `build.sh`.
3. Observe the following failure:
```
/usr/local/share/dotnet/packs/Microsoft.macOS.Sdk/13.3.8825-net8-rc1/targets/Xamarin.Shared.Sdk.targets(303,3): error : Both RuntimeIdentifier and RuntimeIdentifiers were passed on the command line, but only one of them can be set at a time. [/Users/jwostenberg/Code/DotnetMacosNoBuildBug/src/TestApp/TestApp.csproj]
```

It works if you change everything to use .NET 7 (or checkout the `dotnet7/dotnet7` branch).

So while this technically a breaking change, this makes sense. However, I cannot find another workaround. There's another branch, `dotnet8/rids-in-proj`, where I've attempted a workaround by setting `RuntimeIdentifiers` in the project file instead. I get the following warning:

```
/usr/local/share/dotnet/packs/Microsoft.macOS.Sdk/13.3.8825-net8-rc1/targets/Xamarin.Shared.Sdk.targets(299,3): warning : RuntimeIdentifier was set on the command line, and will override the value for RuntimeIdentifiers set in the project file. [/Users/jwostenberg/Code/DotnetMacosNoBuildBug/src/TestApp/TestApp.csproj]
```

which is fine and I can live with, but also the following failure:

```
/usr/local/share/dotnet/sdk/8.0.100-rc.1.23463.5/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.targets(235,5): error NETSDK1085: The 'NoBuild' property was set to true but the 'Build' target was invoked. [/Users/jwostenberg/Code/DotnetMacosNoBuildBug/src/TestLibrary/TestLibrary.csproj]
```

Interestingly, this behavior happens on .NET 7 too (I must have been setting it via the CLI already to work around that). The same behavior happens even if you don't even set `RuntimeIdentifiers` at all for build and publish, specifically.

Additionally, the publish succeeds if you change the FrameworkTarget from `net8.0-macos` to `net8.0` (however it doesn't produce an app executable).

### Environment

CLI, no IDE.
