Auto merge of #26525 - kunalmohan:share-gpu_id_hub, r=jdm

Share single gpu_id_hub among all threads in a process

<!-- Please describe your changes on the following line: -->
An id_hub for a content process is created when a new script thread is created. This is then cloned whenever a new globalscope object is created. The only exception being service workers because they exist in separate processes, for them a new hub is created.
