[Bug]: Missing VAProfileVP9Profile0 : VAEntrypointEncSlice for Kaby Lake when using iHD driver

### Which component impacted?

Encode

### Is it regression? Good in old configuration?

_No response_

### What happened?

1. I ran `vainfo` using **iHD** driver
2. I ran `vainfo` using **i965** driver
3. I compared the both of them and **iHD** doesn't have `VAProfileVP9Profile0 : VAEntrypointEncSlice` but **i965** has it.
4. Video conference and Video calls doesn't use video acceleration when my camera is turned on

### What's the usage scenario when you are seeing the problem?

Video Conference

### What impacted?

I noticed that using `intel_gpu_top` yields no changes in the Video when using Google Meet or Facebook. There should be a rise in percentage in Video when my webcam is turned on but there is none. I suspect that there is no encoder for VP9 in the driver for Intel HD 620 (Kaby Lake). I've read the documentation for my GPU and it should have a VP9 8-bit encoding capability.
