Some improvements to RuleSet shrinking.
<https://webkit.org/b/140534>
Reviewed by Antti Koivisto.
Give an inline capacity (1) to the RuleData Vectors in RuleSet.
The vast majority of Vectors have only a single entry, and this
avoids having to allocate a separate Vector backing store for them.
Also make sure to shrink some Vectors that we weren't already,
like those in RuleFeatureSet.
