Add start_time to resource timing.
<!-- Please describe your changes on the following line: -->
`start_time` property added to `ResourceFetchTiming`, which enables the setting of `start_time` in the `PerformanceEntry` member of `PerformanceResourceTiming`.
Following the specification at https://w3c.github.io/resource-timing/#dfn-starttime, `start_time` is set to the value of `redirect_start` if redirection occurs and the timing allow check passes. Otherwise it has the same value as `fetch_start`.

This needs a lot more hooks before it'll actually be a good
implementation, but for a start it can help get some feedback on if this
is the right way to go about it.
Part of servo/servo#4577
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.

The purpose of this commit is to ensure that the Response object has
access to Timing updates as previously the Response object simply
stored a ResourceFetchTiming struct so updates on ResourceFetchTiming
that were not explicitly done on the Response would not be passed down.
The references to ServoArc are added because Response uses
servo_arc::Arc rather than std::sync::Arc as is used elsewhere. So,
we've switched those other places to servo_arc::Arc instead of switching
Response to std::sync::Arc.
Remove wpt tests for domainLookupStart
Set ResourceAttribute::DomainLookupTime
Move DomainLookupStart timing before HTTP request initialization
Change label of domainLookupStart TAO zero test to PASS
Adjust the from_resource_timing method to initialize domain_lookup_start value
Restore domainLookupsStart test
Implement connectStart in PerformanceResourceTiming
<!-- Please describe your changes on the following line: -->
- Added connectStart where needed (```ResourceFetchTiming```, ```ResourceAttribute```) in ```components/net_traits/lib.rs ```
- Before calling ```client.request``` in ```obtain_response```, we now add the ```connectStart``` attribute (```components/net/http_loader.rs```)
- Updated tests to reflect those changes
