Zhang, Shiyu 0b812b721b Reland "Support Intel VTune ITT API"
This is a reland of 5f5b4b0407

Original change's description:
> Support Intel VTune ITT API
> 
> Add VTune domain support extension to use VTune Domain/Task API and
> tagging trace data for particular JS code block.
> 
> How to use:
> 1. Set `"checkout_ittapi" = True` in the custom_vars section of .gclient
> file to download intel/ittapi by 'gclient sync'
> 2. Build d8 with gn build flag 'v8_enable_vtunetracemark = true'
> 3. Run d8 with flag '--enable-vtune-domain-support'
> 
> The Vtune Domain/Task API can be invoked from JS to mark JS code block.
> You can mark the start of a JS task by
>     vtunedomainmark(domain_name, task_name, "start")
> and the end of a task by
>     vtunedomainmark(domain_name, task_name, "end")
> Tasks can nest.
> 
> The VTune API (ittapi) is integrated as an external third party library
> while the v8_vtune_jit also relies on the VTune ittapi. We have another
> patch almost ready which refactors the v8_vtune_jit related code to
> depend on the third_party/ittapi. We will submit the refactored v8_vtune_jit
> code after this patch stabilized and landed.
