top: exploit that library p-core/e-core identification

I sure hope we won't disappoint the library with these
changes since we're only exploiting one of the two new
enumerators that the immediately prior patch provided.

Now top will be able to offer a visual clue as to each
cpu (thread actually) core association. Is it a P-core
offering multiple threads or a single threaded E-core.

We'll accomplish this feat with a subtle change to the
states portion ('t' toggle) of the summary area. Where
before processors were represented as 'Cpu', they will
now be displayed as 'CpP' (P-core) and 'CpE' (E-core).

[ assuming that new '5' command toggle has been used ]

There are also new provisions for filtering those cpus
by their core type association via the new '5' toggle.
