IOSIntermediateDumpWriter::Close() is intended to close the FD opened
by the in-process handler.
Currently, InProcessHandler::ScopedLockedWriter::~ScopedLockedWriter() does invoke IOSIntermediateDumpWriter::Close().
However, InProcessHandler::Initialize() invokes the utility CreateWriterWithPath() which directly creates an IOSIntermediateDumpWriter. It neither uses ScopedLockedWriter nor invokes Close().
This fixes the issue by:
1) Making IOSIntermediateDumpWriter::~IOSIntermediateDumpWriter() DCHECK() that it's closed
2) Calling IOSIntermediateDumpWriter::Close() from InProcessHandler::~InProcessHandler() and from test files

Testing in beta has shown a few examples of a cropped intermediate dump
still providing useful information, but due to the order intermediate
dump data is written, could be improved.
- Change the order of writing data to the intermediate dump by
increasing the priority of the Exception block from:
Header / Process / System / Threads/ Modules / Exception
to
Header / Process / System / Exception / Threads / Modules
- Annotate minidump reports generated from incomplete intermediate
dumps with the key 'crashpad_intermediate_dump_incomplete'.
- Handle partial exception contexts rather than throwing them away.

Change IOSIntermediateDumpReader to take a new interface that can be
backed by a FilePath (as it is now) or a StringFile byte array, which
can be useful for tests, especially with fuzzing.

size_t is written to intermediate dump properties, but the parser was
reading off_t. off_t can go negative, which is a bad thing to pass
to a std::vector constructor.

Due to the limitations of in-process handling, an intermediate dump file
is written during exceptions. The data is streamed to a file using only
in-process safe methods. The file format is similar to binary JSON,
supporting keyed properties, maps and arrays.
- Property [key:int, length:int, value:intarray]
- StartMap [key:int], followed by repeating Properties until EndMap
- StartArray [key:int], followed by repeating Maps until EndArray
- EndMap, EndArray, EndDocument
Similar to JSON, maps can contain other maps, arrays and properties.
Once loaded, the binary file is read into a set of data structures that
expose the data, maps and arrays.
