fix(arcgis): update arcgis module to use RenderNode instead of externalRenderers

[toddrun]

Closes #9497

Background

ArcGIS JS API 4.29 replaced externalRenderers with the new RenderNode API. The existing @deck.gl/arcgis SceneView integration still depended on externalRenderers, so this PR ports the integration to RenderNode and fixes the rendering issues exposed during that migration.

Change List

• Port the ArcGIS SceneView bridge from externalRenderers to RenderNode.
• Initialize deck/luma resources lazily on the first render() call, which is the earliest point where ArcGIS guarantees a valid WebGL context.
• Capture and reuse the ArcGIS output framebuffer correctly so deck renders into the expected target under RenderNode.
• Fix SceneView alignment under tilt by improving how deck view state, zoom, and altitude are derived from the live ArcGIS camera and focal point.
• Normalize legacy numeric coordinateSystem values in the core shader path so Tile3DLayer / I3SLoader continue to work with the newer string-based shader code.
• Patch @luma.gl/webgl@9.3.2 so shared ArcGIS/deck WebGL state is re-read correctly when ArcGIS changes framebuffer bindings.
• Update the ArcGIS demo apps, tests, and docs to reflect the RenderNode-based integration.

Notes

• The ArcGIS integration now uses a local SceneView RenderNode rather than the old externalRenderers path.
• The luma patch is applied with patch-package during postinstall.
• The core coordinate-system shim is intended to preserve backward compatibility for existing numeric inputs while the rest of deck.gl expects string-valued coordinate systems.

Verification

• Updated the ArcGIS examples to exercise the RenderNode-based SceneView path.
• Added coverage for the core coordinate-system normalization path.

The build failing is actually good news: it means the luma patch is no longer needed. Unfortunately, I don't have immediate bandwidth available to update the dependencies and remove the patch, but this is definitely on "the list" now
