[snapshot] Fix border judgement of PcIsOffHeap()

In the case of using start and size to manage range, the range is start
~ start + size - 1, start + size is out of the range.
The template function IsInRange(T value, U lower_limit, U higher_limit)
judge whether value is in the range lower_limit ~ higher_limit.
IsInRange(pc, start, start + isolate->embedded_blob_size()) misjudge
the case pc == start + isolate->embedded_blob_size()
