3a7e935a86 ios: Handle partial intermediate dumps and exception contexts.
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.

4b86b27773 ios: Add IOSIntermediateDumpInterface.
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.

40cd1b72cf ios: Migrate ios/snapshot to writing intermediate dumps.
This migrates all the logic that used to live in ios/snapshots that
gathers all the various information during an exception.

Everything in InProcessIntermediateDumpHandler is considered
`RUNS-DURING-CRASH`.
