move SkArenaAlloc reset to its own class

SkArenaAlloc has three fields that are used only for reset. Make a
subclass called SkArenaAllocWithReset which has the three
fields, and has the reset functionality.

An example of a reset() that is used instead of using a better scope
is PathOpsAngleAfter in PathOpsAngleTest.cpp.
