x86, bts: detect size of DS fields
Impact: more robust DS feature enumeration
Detect the size of the pointer-type fields in the DS area
configuration via the DTES64 features rather than based on
the cpuid.
Rename a variable to denote that size to reflect that it only
covers the pointer-type fields.
Add more boot-time diagnostics giving the detected size and
the sizes of BTS and PEBS records.
Use the size of the BTS/PEBS record to indicate that the
respective feature is not available (if the record size is zero).
