The extra_memory_ranges stored in the intermediate dump and used by
gwp-asan via the ProcessSnapshot are not needed in the minidump. If this
memory were stored in the minidump with gwp-asan, this would double the
size of every iOS minidump.
Instead, add a second bag that is stored in the intermediate dump but
not written to the minidump. Expose an iOS only ProcessSnapshot API that
can be used by the gwp-asan analyzer to use the extra_memory_ranges without increasing the minidump file size.

Port set_extra_memory_ranges support to iOS. Because iOS crashes
are processed in two parts, store the memory data itself (not just
the range) in the intermediate dump, and on post-crash processing,
move the memory to ProcessSnapshot ExtraMemory.

doc/support/crashpad.doxy is updated with:
```
% doxygen -u doc/support/crashpad.doxy
[…]
% doxygen -v
1.13.2
```
Additional updates to doc/support/crashpad.doxy are made:
- The settings for `DISABLE_INDEX` and `GENERATE_TREEVIEW` are updated,
as Doxygen’s defaults have changed. This switches from the
top-of-page index to the side-of-page tree view.
- The TODO and Deprecated sections have become more prominent under the
side-of-page tree view than they were with the top-of-page index, and
they’re not very useful in Crashpad documentation, so they’re
disabled by setting `GENERATE_TODOLIST` and `GENERATE_DEPRECATEDLIST`
appropriately. The similar (but unused in Crashpad)
`GENERATE_TESTLIST` and `GENERATE_BUGLIST` are also disabled.
- `USE_DOT` is now set, to use `dot` from GraphViz to generate SVG
diagrams. These look better than the PNGs that Doxygen generated
without `dot`. `DOT_COMMON_ATTR` and `DOT_EDGE_ATTR` are set to make
the fonts used in GraphViz-generated SVGs match those used in
Doxygen-generated HTML/CSS.
- `EXCLUDE` has been updated to drop directories that no longer exist
(compat/non_cxx11_lib) and add ones that now do (compat/android,
compat/ios, and compat/linux).
- Some values that were otherwise unused in doc/support/crashpad.doxy
are set back to their default values. The differences from the
default configuration are shown with `doxygen -x
doc/support/crashpad.doxy`, and a configuration template with default
values can be generated for inspection with `doxygen -g
/tmp/template.doxy`. The tags affected are:
- `MATHJAX_RELPATH`, unused since `USE_MATHJAX` is `NO`.
- `LATEX_CMD_NAME` and `LATEX_BIB_STYLE`, unused since `USE_LATEX`
is `NO`).
- `EXCLUDE_PATTERNS`, unused since `EXCLUDE_PATH` is empty.
doc/support/doxygen_crashpad.css is updated to change the non-monospaced
font from Open Sans to Noto Sans. It is also updated to use the CSS
properties Doxygen defines for the purpose, rather than monkeying around
with custom selectors. The properties can be discovered by running
`doxygen -w html header.html footer.html customdoxygen.css
doc/support/crashpad.doxy` and reviewing customdoxygen.css.
doc/support/generate.sh is updated to further execute
doc/support/generate_doxygen.py by invoking directly and relying on its
`#!/usr/bin/env python3` line rather than invoking via `python`, which
is no longer available on many systems. doc/support/generate_doxygen.py
has already been Python 3-compatible since f88a116c0e2e
(https://chromium-review.googlesource.com/c/3542572, 2022-03-23).
Finally, there are a number of changes to fix Doxygen warnings produced
by the new Doxygen version or because of new code that has not yet been
run through Doxygen during a test run.

This CL introduces a new crash key 'crashpad_uptime_ns' that records the
number of nanoseconds between when Crashpad was initialized and when a
snapshot is generated.
Crashpad minidumps record the MDRawMiscInfo process_create_time using a
sysctl(KERN_PROC).kp_proc.p_starttime. This time is used to display the
'uptime' of a process. However, iOS 15 and later has a feature that
'prewarms' the app to reduce the amount of time the user waits before
the app is usable. This mean crashes that may happen immediately on
startup would appear to happen minutes or hours after process creation
time.
While initial implementations of prewarming would include some parts of
main, since iOS16 prewarming is complete before main, and therefore
before Crashpad is typically initialized.

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.
#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.
