build: don't use AOT publishing on unsupported RIDs

.NET 8 only supports AOT compilation on a subset of .NET runtimes,
namely:

- win-x64
- win-arm64
- osx-x64
- osx-arm64
- linux-x64
- linux-arm64

This means we need to do something else of our win-x86 and linux-arm
(32-bit) targets.

For these two, let's use the combo of SingleFile+Trimmed+ReadyToRun
publishing options instead to keep both file sizes down, and reduce
runtime performance hits from JIT.

.NET 9 and later support AOT for win-x86 and linux-arm (32-bit) targets,
but since we only prefer to target LTS releases of .NET, we'll have to
wait for .NET 10 (the next LTS release) to do AOT on _all_ our
platforms.

Given that .NET 10 GA is just around the corner, this shouldn't be too
long to wait.
