Follow-up on https://issuetracker.google.com/247066500

For the following scenario:

// app/build.gradle
dependencies {
  implementation(platform(project(":platform")))
}

// platform.build.gradle
plugins {
  'java-platform'
}

javaPlatform {
  allowDependencies()
}

dependencies {
  api("androidx.core:core-ktx:1.7.0")
}

When getting the compile/runtime dependencies for app, androidx.core:core-ktx:1.7.0 will be missing (this scenario is captured in JavaPlatformDependencyTest).

AGP models should contain transitive dependencies of the platform project and:

if AGP models contain the :platform project we need to filter out that dependency on the IDE side as this project cannot have any sources
we can also omit the :platform project fully, but this implies that dependency graph information is incomplete
