Inspector: Add Memory tab and improve Renderer.info

[sunag]

Related issue: #31869

Description

Adds initial support for memory analysis.

The PR also exposed a need to improve the architecture in the Backend functions such as updateSampler and updateBindings so that tracking buffers or interfaces becomes clearer and easier to sync using create/destroy, which should also help readability in the Timeline tab.

The memory analysis is still not considering the buffers used in the final screen output, the size will be a little smaller as a consequence.

This helped find a bug almost immediately in webgpu_loader_gltf, where it wasn’t disposing of the previous model.
