The "Address" type is V8's general-purpose type for manipulating memory
addresses. Per the C++ spec, pointer arithmetic and pointer comparisons
are undefined behavior except within the same array; since we generally
don't operate within a C++ array, our general-purpose type shouldn't be
a pointer type.

Previously we could not support these due to their unique memory layout
including off-heap backing store allocations. We now serialize these
allocations and then fix-up references to them in the PostProcess step
of deserialization.

Changes include:
- Adding V8_EXPORT macro for SnapshotCreator
- Removing outdated DCHECKs.
- Allow nullptr as external reference. This required a...
- Refactoring of hashmaps used by the serializer.
- Remove external references for counters. These are not used
anywhere for isolates that are being serialized.
- Put template infos into the partial snapshot cache.
- Remove unnecessary presubmit check for external references.
mksnapshot crashes if external references are missing.

Make MatchFun a template parameter in TemplateHashMapImpl, moving the
PointersMatch function down to an implementation which extends
TemplateHashMapImpl to void* key and value (i.e. the same as the current
HashMap and ZoneHashMap typedefs).
This will allow other instantiations of TemplateHashMapImpl, with
different MatchFun values, e.g. std::equal_to, to have their key
equality test inlined, rather than calling a function pointer,

We ported hashmap.h into libsampler as a workaround before, so the main focus of
this patch is to reduce code duplication. This patch moves the hashmap into
src/base as well as creates DefaultAllocationPolicy using malloc and free.

Currently attached references are only used for global proxy, source
string and code stubs. Mid-term future we want to use attached
references for arbitrary objects (in fixed order) provided from outside.
This change renames BackReference to SerializerReference to include both
back references and attached references.
