Auto merge of #23990 - tomasdivito:add-secure-connection-start, r=jdm

Add secure connection start

Implementing `secure_connection_start` as well as we can, this is related to #21268

We are setting the value as well as we can since we don't have a way to know if we are currently using a secure transport or where the handshake before the connection is done as the spec says on the step 15 [https://w3c.github.io/resource-timing/#sec-process](https://w3c.github.io/resource-timing/#sec-process)

Regarding the Timing Allow Check, that's being done on another PR by another person which will take care of setting the rest of the values on `PerformaceResourceTiming` to Zero and prevent them to set them any other way.

I'm currently setting the `secure_connection_time` using `precise_time_ms()` as the `connection_start` and `connection_end` are set that way... but other attributes inside `PerformanceResourceTiming` are set using `precise_time

Another thing, the issue talks about setting `redirect_start` but I'm not really sure if it's related, if so I can look up into that too... I might have just read and thought it was all about secure connection start.
