This change adds a new WebGPU web-compat content settings type. This would allow showing a brand new "Webgpu" toggle inside the Brave shields > "Block fingerprinting" secondary UI.
This change also connects the current webgpu scrubbing to this new content setting type which was webgl before. This allows the users to turn on/off the fingerprinting protections selectively on WebGPU APIs w/o changing WebGL.
