[dotnet] aotdata files go in the same directory as the assemblies. (#12058)

aotdata files go next to the assemblies, not next to the executable. This does
not make a difference for mobile platforms (because it's the same location),
but it matters for Mac Catalyst / macOS, where assemblies are not located next
to the executable.
