perf arm-spe: Define metadata header version 2
The first version's metadata header structure doesn't include a field to indicate a header version, which is not friendly for extension. Define the metadata version 2 format with a new header structure and extend per CPU's metadata. In the meantime, the old metadata header will still be supported for backward compatibility.
