Measure selectors.

Browse source 
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.
