Remove misleading BrowserContextKeyedAPI comment.

Remove misleading BrowserContextKeyedAPI comment.

The comment suggests that one can manage the factory instance using the Singleton class.
That is not possible as Singleton<T> has private methods only and declares only T::GetInstance as friend.
BrowserContextKeyedAPIFactory<X>::GetInstance cannot be defined by users however.

That misleading comment was added here

Jeffrey, please owner review.

Btw. what do you think about the suggested non-leaky LazyInstance? Shouldn't we
by default use a leaky LazyInstance for such factories?

LGTM; thanks for digging to find where the comment was introduced.

I *think* every use of LazyInstance should actually be LazyInstance::Leaky, but
that makes me wonder why the non-leaky version still exists.

Drive-by because I'm CC'ed on this CL for some reason: yoz isn't on the team
anymore, so I'll track down changing his code review name to "do not send
reviews"
