4581a355b1 ios: Limit depth of intermediate dump parser.
Limit the parser stack to 10 to prevent malformed intermediate dumps
from causing a stack overflow.

94242690d5 ios: Check dyld_image_info->imageFilePath for nullptr.
It seems on iOS 14, sometimes this path can be empty. Passing nullptr
to strlen will crash. Also fixes an incorrect file path length for
the dyldPath.

This fixes a _LIBCPP_ASSERT vector[] index out of bounds error, caught
by fuzzer.

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`.
