cpu/intel: Add SMBIOS Socket BGA1744 type

Enable SMBIOS Processor Upgrade Type reporting for Socket BGA1744.

- Add CPU_INTEL_SOCKET_BGA1744 Kconfig option
- Add socket_BGA1744 subdirectory to build system
- Map to PROCESSOR_UPGRADE_SOCKET_BGA1744 in SMBIOS Type 4

TEST=Built for mc_rpl1, verified `dmidecode -t processor | grep Upgrade`
     shows "Socket BGA1744"
