Support variantOf in add calls

[madisp]

It's used to achieve artifact type selection together with version catalogs, e.g.:

dependencies {
  add("myconfig", variantOf(libs.foo) {
    artifactType("tar")
  })
}

currently fails with:

1: extraneous input 'libs.foo' expecting ')', 2: extraneous input ')' expecting {'}', ID}

Thanks for the issue. Could you provide a minimal reproducer?

The bit I had was:

add("orchestratorApks", variantOf(libs.apks.orchestrator) {
  artifactType("apk")
})

and libs.apks.orchestrator was this in libs.versions.toml:

apks-orchestrator = "androidx.test:orchestrator:1.4.2"

On my side turns out I didn't need the artifactType at all, it resolved to the correct packaging as it was the default but for some libraries you may have multiple artifact types and may want to select a specific one.
