[core] send CDP type by mime type

[Kudo]

Why

previously we send the CDP request/response type as fetch always. we should send other types like image when the resources are images
close ENG-8609

How

based on mime type to send the corresponding CDP type. for unknown data, we will send other. so we will never send fetch type anymore, because we cannot differentiate whether the requests are coming from fetch or other requests like image or native calls.

Test Plan

• tested on bare-expo
  

• added unit test
