Chromium moved base::size() to base/cxx17_backports.h, so do the same in
mini_chromium and update the users in Crashpad.
Roll mini_chromium to 2f06f83f to make the new base header available.

This is a follow-up to c8a016b99d97, following the post-landing
discussion at
https://chromium-review.googlesource.com/c/crashpad/crashpad/+/1393921/5#message-2058541d8c4505d20a990ab7734cd758e437a5f7
base::size, and std::size that will eventually replace it when C++17 is
assured, does not allow the size of non-static data members to be taken
in constant expression context. The remaining uses of ArraySize are in:
minidump/minidump_exception_writer.cc (×1)
minidump/minidump_system_info_writer.cc (×2, also uses base::size)
snapshot/cpu_context.cc (×4, also uses base::size)
util/misc/arraysize_test.cc (×10, of course)
The first of these occurs when initializing a constexpr variable. All
others are in expressions used with static_assert.

Update mini_chromium to 737433ebade4d446643c6c07daae02a67e8deccao

readdir_r() is a thread-safe version of readdir(), although readdir() is
not particularly thread-unsafe with most usage. The dirent* returned by
readdir() can only be invalidated by a subsequent readdir() or
closedir() on the same DIR*. In typical usage, where a returned dirent*
is used exclusively within a loop around readdir() and is not expected
to outlive that loop, there are no lifetime or thread-safety issues with
the use of readdir().
readdir_r() may be harmful in certain situations because its buffer is
not explicitly sized, and attempts to provide a suitably sized buffer
dynamically (which, incidentally, our code did not do) are subject to a
race condition.

glibc has already deprecated readdir_r(), and all Linux (including
Android) code was already using readdir(). This change eliminates
variant codepaths. It delegates buffer sizing (which we weren’t doing
correctly) to the C library, which also has more options at its disposal
to avoid races in sizing that buffer.

The "file-limit" annotation has shown that the system as a whole is not
likely to be out of file descriptors globally. It’s possible that a file
descriptor leak in crashpad_handler itself is responsible for certain
crashes. Add a count of the number of open files in the handler process
to this annotation to test this theory.

The "file-limit" annotation will be used to confirm the theory that
certain crashes are caused by systems at or near their file descriptor
table size limits.
The annotation records the system-wide kern.num_files and kern.maxfiles
values, and the process-specific current and maximum file descriptor
limits.
The annotation will be set on crashpad_handler startup, and will be
refreshed every time an exception is handled and every time the upload
thread processes a pending report.
It’s expected that this annotation will be removed after enough data has
been collected to confirm the theory. However, the principle is useful
enough that we may want to provide this feature more generally under
bugs 19 or 21.
