Remove threading primitives from ParseHTMLOnMainThread

of crossThreadBind in HTMLDocumentParser/BackgroundHTMLParser,
which introduces unecessary copies if we're not actually crossing
threads.

Add an experiment group via Settings to tokenize synchronously

This patch adds an experiment group that tokenizes synchronously
on the main thread in response to a recieve data IPC.

If this regresses performance, we can augment the CL slightly
to only synchronously tokenize when the main parser has no
work.

Your CL relies on deprecated CQ feature(s):
 * Specifying master names in CQ_INCLUDE_TRYBOTS part of description without
"master." prefix is deprecated:

CLs for remote refs other than refs/pending/heads/master must contain NOTRY=true
and NOPRESUBMIT=true in order for the CQ to process them
