First-chance-handlers should also run even with disabled crashpad

To avoid unnecessary duplication of potentially large memory regions,
the iOS MemorySnapshot data is owned by the intermediate dump. When
merging two iOS memory snapshots, it's necessary to copy the merged
data into a vector owned by the memory snapshot itself.
Previously the merged snapshot just contained the original data, which
leads to a heap overrun.

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

- Handle partial exception contexts rather than throwing them away.

The size of dyld_all_image_infos didn't change, but the last 128 bit
of `reserved` moved out of `reserved` and got names.
On 64-bit, that's straightforward -- just move two uint64s out of the
array into fields.
On 32-bit, it's fairly awkward: It's 4 of the uintptr_t `reserved`
array, which means `UIntPtr, reserved, [4]` would have to diverge
between 32-bit and 64-bit, and also shared_cache_fs_obj_id would
straddle the `end_v14` boundary. Since macOS 12.0 doesn't support
32-bit builds, just punt on this for 32-bit. (This might possibly
mean that crashpad-on-apple-watch might not compile, but that's
a build configuration that doesn't exist.)

The iOS crashpad client was mistakenly setting the process annotations
(typically things like version and product name) when converting the
intermediate dump into a minidump. This is incorrect, as those
annotations are determined at intermediate dump creation time.
Instead, correctly write those annotations during intermediate dump
creation. Passing extra annotations during intermediate dump to
minidump is still supported.

This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.

This will accommodate moving third_party/mini_chromium around.
The default location is unchanged for now.
There are GN variables that may need to be updated when Fuchsia's source
re-organizes its layout:
* mini_chromium_source_parent : this contains a BUILD.gn with groups and
encloses the mini_chromium_source_root. This is controlled by the
structure of the project that depends on this project.
* _mini_chromium_source_root : this is what is normally checked out from
git, the upstream source directory
* mini_chromium_import_root : points inside source_root to make GN files
accessible.
This first step breaks out case logic for "if (crashpad_is_in_fuchsia)"
even if the value is unchanged for now. This will faciliate a smaller
change when Fuchsia re-structures third_party sources.

The load bias is documented to be the difference between
the preferred and actual load address for a module, but
is declared as an unsigned number, and math using it relies
on it being a pointer-precisioned two's complement number
that might cause over- or under-flow.
ElfImageReader and DebugRendezvous both provide ways to get
the load bias for a module and are corroborated in tests.
However, the load bias computed by DebugRendezvous does
not have access to the preferred address, so there is not
enough information to determine the signedness to use with
a VMOffset.
This patch compares the load biases modulo the numeric range
for a pointer to ignore the signedness of the value.
Also update the test module to trigger a negative load bias.
