Add 46 Xeon CPUs with thread counts from Intel spec pages

[Seungpyo1007]

46 Xeon SKUs (Broadwell 26, Haswell 15, Skylake 3, Sandy Bridge 2) that were held back from #265. Their Wikipedia tables list cores but not threads, and the parser no longer guesses threads (GetTechAPI/TechEngine#93).

• Thread counts come from Intel's official product-specification pages ("Total Threads"). Each record cites both the Wikipedia list page and its intel.com spec page.
• Every value is either cores or 2 × cores. I spot-checked three pages directly (D-1513N 4C/8T, D-1543N 8C/16T, E7-4809 v4 8C/16T).
• The other 13 SKUs in the batch had no reachable Intel page and stay out. The remaining 57 Ivy Bridge and Nehalem candidates are a later batch.
• verified: false. Architecture, segment and folder follow Add 124 missing Intel Xeon, Celeron and Pentium CPUs from Wikipedia sub-pages #265.

python -m app.validate passes.
