Closes #34519.
Description
The PR makes textures don't keep renderer memory alive even if
renderer.dispose()has been called. That happens because dispose event listeners keep references to internal entities and they are never removed in dispose. This change applies the same principle fromWebGPURenderertoWebGLRenderer. Similar to #34529, we use a combination ofWeakRefandFinalizationRegistryto make sure we can implement aWebGLTextures.dispose()the renderer can call to clean everything up.
