This is just for caching and reducing look ups. Minor performance boost.

If anything, it's just a little cleaner.

Summary by CodeRabbit

• Performance Improvements
  • Improved clustered rendering efficiency by reducing unnecessary buffer updates and computing render/shadow pass counts up front.
  • Streamlined render-scene parameter sourcing and debug decision handling to avoid repeated lookups.
  • Updated camera data handling to pass transform and projection parameters by reference, reducing copying.
• Bug Fixes
  • Tightened cast validity checks in the script analyzer to use strict built-in conversion rules, improving correctness of reported cast outcomes.

Walkthrough

The PR refactors clustered rendering to cache scene data and debug state across render passes, updates camera parameter passing to const references, and tightens GDScript builtin cast validation.

Changes

Clustered Renderer Optimization

Layer / File(s)	Summary
Instance buffer and shadow loop optimization servers/rendering/renderer_rd/forward_clustered/render_forward_clustered.cpp	_update_instance_data_buffer() uses a direct instance-data reference with an empty-data early return, and _pre_opaque_render() iterates shadow passes using precomputed counts.
Scene render refactoring with local caching servers/rendering/renderer_rd/forward_clustered/render_forward_clustered.cpp	_render_scene() introduces a local scene_data pointer, caches debug draw mode into booleans, computes motion-vector requirements, and updates scene-data assignments and GI setup to use the cached pointer.
Render passes using cached scene data servers/rendering/renderer_rd/forward_clustered/render_forward_clustered.cpp	Opaque, motion, alpha, depth-prepass, sky radiance, debug probe, SSS/SSR, FSR2, TAA, MetalFX, and debug SDFGI paths now source camera, projection, jitter, and debug-state values from scene_data and cached debug flags.

Camera and Cast Validation

Layer / File(s)	Summary
Camera parameter passing optimization servers/rendering/renderer_scene_render.h, servers/rendering/renderer_scene_render.cpp	RendererSceneRender::CameraData::set_camera now takes Transform3D and Projection by const reference in both the declaration and definition.
Strict builtin cast checks modules/gdscript/gdscript_analyzer.cpp	GDScriptAnalyzer::reduce_cast() switches builtin-to-builtin compatibility from Variant::can_convert() to Variant::can_convert_strict().

Tested & it does in fact give a minor performance boost. Code lgtm
