fix: add CPU detection for Intel Emerald Rapids and newer processors

Problem:
Intel Xeon Platinum 8575C (Emerald Rapids, model 207 = exmodel 12, model 15)
was incorrectly detected as PRESCOTT (Pentium 4 era) instead of SAPPHIRERAPIDS.

Root cause:
1. In get_corename() function, case 12 (exmodel 12) only handled model 6
   (Arrow Lake) but missed model 15 (Emerald Rapids)
2. Missing break statement caused fall-through to case 15 (family 15,
   which is Pentium 4), returning CORE_PRESCOTT incorrectly
3. dynamic.c lacked support for exmodel 10-12 newer Intel processors

Changes:
- cpuid_x86.c: Add case 15 (Emerald Rapids) to exmodel 12 switch and
  add missing break statement
- dynamic.c: Add runtime detection support for:
  - Exmodel 10: Meteor Lake (model 0, 10), Granite Rapids (model 13)
  - Exmodel 11: Raptor Lake, Alder Lake N (model 7, 10, 14, 15)
  - Exmodel 12: Arrow Lake (model 6), Emerald Rapids (model 15)
