[Projection tooling] Surface build errors

[jkurdek]

When using build.sh to build the project the tooling is run on the integration tests. If a fail occurs during that the errors are not forwarded to the developer.

Swift.Bindings.Integration.Tests failed with 2 error(s) (1,5s)
    EXEC : error : emit-module command failed with exit code 1 (use -v to see invocation)
    /Users/jeremi/Repos/runtimelab/src/Swift.Bindings/tests/IntegrationTests/Swift.Bindings.Integration.Tests.csproj(22,5): error MSB3073: The command "cd /Users/jeremi/Repos/runtimelab/artifacts/bin/Swift.Bindings.Integration.Tests/Debug/net9.0 && cmake /Users/jeremi/Repos/runtimelab/src/Swift.Bindings/tests/IntegrationTests/ && make" exited with code 2.

So we are able to see the output when running build.sh with greater verbosity. Might be good enough for now.
