Implement experimental WebGPU support (#1238)

* Web gpu execution MVP

Ready infrastructure for wgpu experimentation

Start implementing simple gpu test case

Fix Extract Node not working with nested networks

Convert inputs for extracted node to network inputs

Fix missing cors headers

Feature gate gcore to make it once again no-std compatible

Add skeleton structure gpu shader

Work on gpu node graph output saving

Fix Get and Set nodes

Fix storage nodes

Fix shader construction errors -> spirv errors

Add unsafe version

Add once cell node
