David Benjamin 3af8dba67e Modernize the Arm cpuinfo parser a bit
Now that we're C++, we can just use std::string_view here, rather than
making our own. Also since this is just a C++ file now, use the C++
style to name these functions. Squatting bssl::SplitStringView seems a
bit rude, so wrap it in a little namespace.

While I'm here, now that we only need to read /proc/cpuinfo in this
workaround path (we used to always need it), don't bother even opening
the file most of the time.
