fix: conditionally include iOS/macOS targets only on macOS

- Add MSBuild condition to only include net8.0-ios and net8.0-maccatalyst on macOS
- On Linux/Windows, only net8.0 is included as a target framework
- Fixes GitHub dependency submission failing on Ubuntu runners
- Remove wasm-tools installation from test workflow (no longer needed)

This fixes the root cause of NETSDK1147 errors on non-macOS platforms.
