[benchmarks] CMP-10298: Extract Compose scene API into versioned modules for cross-version compatibility

[Nikita Lipsky (pjBooms)]

Benchmarks used internal Compose UI API (CanvasLayersComposeScene,
ComposeScene.render) directly in MeasureComposable.kt, which broke
when compose-multiplatform-core#3012 replaced the single render()
method with FrameRecomposer + measureAndLayout() + draw() phases.

Introduce a versioned abstraction layer:

• :compose-scene-api — BenchmarkComposeScene interface (setContent,
  render, close) depending only on public Compose API.
• :compose-scene-impl-1 — implementation for Compose versions before
  PR compose-multiplatform-core#3012 (≤1.11.x, 1.12.0-alpha01, alpha02 dev builds <4221),
  using ComposeScene.render(canvas, nanoTime).
• :compose-scene-impl-2 — implementation for Compose versions after
  PR compose-multiplatform-core#3012 (1.12.0-alpha02+dev4221+), using FrameRecomposer with
  performFrame(), measureAndLayout(), and draw().

The correct impl module is auto-selected in settings.gradle.kts
based on the Compose version (from libs.versions.toml or
-Pcompose.version), and mapped as :compose-scene-impl so
MeasureComposable.kt uses only the stable BenchmarkComposeScene
interface without any @InternalComposeUiApi usage.

Fixes CMP-10298
