Move some WebGPU modules from core to addons.

Description

As mentioned in #29483 (comment), a lot of typical addons are currently placed in core. To minimize the size of build files, some of these should be moved back to the examples/jsm/ directory.

I have created a table to lists modules in src/nodes/display with suggested new locations. We can add modules from other directories as well and of course discuss the intended locations.

Module	Location
src/node/display/AfterImageNode.js	Addons
src/node/display/AnaglyphPassNode.js	Addons
src/node/display/AnamorphicNode.js	Addons
src/node/display/BleachBypass.js	Addons
src/node/display/BlendMode.js	Core
src/node/display/BloomNode.js	Addons
src/node/display/BumpMapNode.js	Core
src/node/display/ColorAdjustment.js	Core
src/node/display/ColorSpaceFunctions.js	Core
src/node/display/ColorSpaceNode.js	Core
src/node/display/DenoiseNode.js	Addons
src/node/display/DepthOfFieldNode.js	Addons
src/node/display/DotScreenNode.js	Addons
src/node/display/FilmNode.js	Addons
src/node/display/FrontFacingNode.js	Core
src/node/display/FXAANode.js	Addons
src/node/display/GaussianBlurNode.js	Addons
src/node/display/GTAONode.js	Addons
src/node/display/Lut3DNode.js	Addons
src/node/display/MotionBlur.js	Addons
src/node/display/NormalMapNode.js	Core
src/node/display/ParallaxBarrierPassNode.js	Addons
src/node/display/PassNode.js	Core
src/node/display/PixelationPassNode.js	Addons
src/node/display/PosterizeNode.js	Core
src/node/display/RenderOutputNode.js	Core
src/node/display/RGBShiftNode.js	Addons
src/node/display/ScreenNode.js	Core
src/node/display/Sepia.js	Addons
src/node/display/SobelOperatorNode.js	Addons
src/node/display/SSAAPassNode.js	Addons
src/node/display/StereoCompositePassNode.js	Addons
src/node/display/StereoPassNode.js	Addons
src/node/display/ToneMappingFunctions.js	Core
src/node/display/ToonOutlinePassNode.js	Core
src/node/display/TransitionNode.js	Addons
src/node/display/ViewportDepthNode.js	Core
src/node/display/ViewportDepthTextureNode.js	Core
src/node/display/ViewportSharedTextureNode.js	Core
src/node/display/ViewportTextureNode.js	Core

Is everyone fine with moving the above addons into examples/jsm/tsl/display/?
