Rename BUFFERPIN wait event class to BUFFER

Browse Source 
In an upcoming patch more wait events will be added to the wait event
class (for buffer locking), making the current name too
specific. Alternatively we could introduce a dedicated wait event class for
those, but it seems somewhat confusing to have a BUFFERPIN and a BUFFER wait
event class.
