Mark Mentovai cc166d71f4 Use base::size where appropriate, and ArraySize elsewhere
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.

Includes:
Update mini_chromium to 737433ebade4d446643c6c07daae02a67e8deccao

f701716d9546 Add Windows ARM64 build target to mini_chromium
87a95a3d6ac2 Remove the arraysize macro
1f7255ead1f7 Placate MSVC in areas of base::size usage
737433ebade4 Add cast
