Update HiltGradlePlugin to AGP 9.

This required a number of changes:

   * Update Gradle 8.14.3 -> 9.2.0
   * Update shadow plugin from `com.github.johnrengelman.shadow:8.1.1` to 'com.gradleup.shadow:9.2.2' (old artifact doesn't support Gradle 9).
   * Update HiltGradlePlugin to 9.0.0-beta02:
     * Migrate `BaseExtension` to `AndroidComponentsExtension`
     * Migrate `BaseVariant` to `Component`
     * Migrate `variant.javaCompileOutput.classpath` to `variant.compileClasspath`
     * Migrate `variant.javaCompileOutput.destinationDirectory` to `variant.artifacts.use(HiltCopyTask).toGet()`
     * Migrate `variant.javaCompileOutput.options.bootstrapClasspath` with `androidExtension.sdkComponents.bootClasspath`
     * Migrate `variant.javaCompileOutput.options.compilerArgumentProviders` with `variant.javaCompilation.annotationProcessor.argumentProviders`
     * `project.buildDir = ...` to `project.layout.buildDirectory.set(...)`
   * Update HiltGradlePlugin tests to use AGP 9.0.0-beta02:
     * Migrate to builtin kotlin
       * remove 'kotlin-android'
       * replace 'kotlin-kapt' with 'legacy-kapt'
     * Migrate javatests/artifacts/hilt-android/simple/app/build.gradle to kts and replace GradleVersion with custom AgpVersion.
       The GradleVersion does not work with APG versions like 9.0.0-beta02, so I had to do this with custom parsing.
     * remove `android.kotlinOptions` (removed in AGP 9)
