style: remove selector_map::find_push.
It has a single caller and is overly generic, which is going to make harder to
add fallible allocations to it.

"javascript:" urls: execute in correct global scope
<!-- Please describe your changes on the following line: -->
#### Summary
This pull request makes `javascript:` urls execute in the correct global scope.
#### Example
```html
<script> var x = 4; </script>
<!-- this branch: logs "4" -->
<!-- master: undefined variable error -->
<a href="javascript:console.log(x)">link</a>
```
#### Questions
I'm new to servo and rust, so I'm unsure about these changes. In particular:
* What's the appropriate place to evaluate the js?
* I moved it to `handle_navigate`, but I'm not sure if this will catch all occurrences of `javascript:` urls. I also don't know if this will execute in the correct thread and the correct window.
* What should I do with the result of the js evaluation?
* I just ignored it. The previous behavior displayed it as the content of a new page load.

A single transition value that includes 'none' for transition-property is
valid, so we should store whole specified values (if it's valid). Whereas,
the spec [1] clearly says for the case where there are multiple entries;
If there is more than one <single-transition> in the shorthand, and any of
the transitions has none as the <single-transition-property>, then the
declaration is invalid.
'none 2s linear 2s' is a test case for the former, '1s width, 2s none' is a
test case for the latter.
Note that with this patch, 'transition: none' is serialized as 'none 0s ease 0s'
instead of 'none' but it matches Gecko.

Keep the unit of the serialization of specified::CalcLengthOrPercentage.
For the serialization of specified values of calc(), we should keep the
units of absolute lengths, so use AbsoluteLength.

Remove this block and unindent the code one level.
Doing this required cloning `load_data.url` so that we could
later mutate `load_data.url` in the same block.

- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [X] These changes fix#18109
- [X] There are tests for these changes. I enabled the peformance-timeline API WPTs but some of them are still failing because of implementation bugs or missing APIs (Resource Timing, for instance) the tests are dependent of. I'll file issues to fix them.
