Objective

Fixes #25342

Solution

Refactor ShaderCache to make it only holds processed shader source instead of wgpu::ShaderModule and make load_module async.

Testing

Tested shader_material with an invalid shader on native with file_watcher hot-reloading and on web.

Note: blocked by gfx-rs/wgpu#10039. Currently panics on webgpu due to wgpu popErrorScope bug.
