Move the "Trait Bounds" slide right after "Generic Functions". (google#2589)

The "Generic Data Types" slide now uses trait bounds, which makes it
very confusing to explain. (e.g., "ignore this trait bound stuff while I
explain why we need to stutter to describe the generic args on an impl
block").

Also in the "Generic Functions" slide, the speaker notes talks about how
we essentially need to treat the generic args as black boxes - this is
probably more important to address then talking about all the ways you
can make things generic.
