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] 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.

Measure selectors.
This patch adds measurement of Selectors within StyleRule. This requires
exposing the pointer within ThinArc.
The patch also adds measurement of the several CssRule variants, in order to
measure nested CssRules (and PropertyDeclarationBlocks) within them:
DocumentRule, MediaRule, PageRule, SupportsRule.

stylo: Pass the @page values to precomputed pseudo element declarations
We were parsing @page rules correctly and serializing for cssom when we
we need. But we weren't actually including them to the pseudo element
declarations when we need to print a page.

Use a 1-element smallvec for selector lists.
Profiling shows this reducing parsing time by a few milliseconds on the tp6 facebook case. The gtest benchmark with the same concatenated stylesheets also shows a significant improvement.
