In D25705, I added a new arenaId member to the js::BaseAllocPolicy. This
increased the size of everything that uses a JS AllocPolicy, which is a
lot.
This change follows suit from earlier work, which is to make everything
allocation-related have an "arena" version and a "default" version that
uses the arena version with the implied default arena.
StringBuffer is then changed to use this new functionity to define its
own alloc policy that uses the new StringBufferArena.

Several areas of JS code abstract their memory allocation logic behind an
AllocPolicy. Since these allocations may now need to be in different arenas,
each AllocPolicy will need to be assigned a Mozjemalloc arena that it will
use for all its allocations.

JSONWriter currently calls new and delete indirectly through mozilla::MakeUnique to allocate a buffer. Becuase of this, the methods of this class cannot be invoked within Spidermonkey due to https://searchfox.org/mozilla-central/source/config/check_vanilla_allocations.py#6-14. Therefore, JSONWriter needs an AllocPolicy template parameter so that the allocation and deallocation routines can be changed to match the JS AllocPolicy when invoked within SpiderMonkey.
