The ProcessInfo initialization fails on ARM on Windows with
'ReadProcessData failed'.
The 64-bit detection logic only checks whether it's on x64 and ignores
ARM64. On ARM64, the ReadProcessData template should be instantiated
with internal::Traits64 as it is on x64.
Test: Run crashpad_tests on ARM, 'ReadProcessData failed' is gone
