Remove Characteristics manipulation in Collectors

Collector.Characteristics is used only for optimizations
and unused by current GWT emulation.
Removing logic around the piping of Characteristics
is slightly incompatible with JRE however gets rid
of the all the extra logic required in most code paths
for streams plus drops the extra EnumSet dependency from
the code and compiler optimization will probably drop
Characteristics class and its metadata as well.
