Migrate query dispatch up from llcache to hlcache

As a first step in refactoring query handling to be managed
by `browser_window`, this migrates the calling of the query
handler from the llcache object code up to the hlcache.

In theory this may result in multiple queries happening for one
object, but we mitigate multiple-responses in the llcache so
all should be well.
