[Feature]: Add initiator to HAR recording

[ducalpha]

Feature request

Current HAR recording does not include _initator of HTTP requests. DevTools dump from UI contains this information. HTTPRequest with the initiator feature is now supported by Puppeteer.

What is your use case for it?

[ducalpha]

I need the initiator information to analyze data traffic originated from different sources (e.g., which scripts) of a web page to identify data leakage (i.e., privacy & security issues) on websites. The initiator can also be used in other use cases such as web-page performance analysis and testing/debugging.

It will also be very useful if initiator information is available from the request object.
