[v3,0/5] hw/smbios: add core_count2 to smbios table type 4

The SMBIOS 3.0 specification provides the ability to reflect over
255 cores. The 64-bit entry point has been used for a while, but
structure type 4 has not been updated before, so the dmidecode output
looked like this (-smp 280):

    Handle 0x0400, DMI type 4, 42 bytes
    Processor Information
    ...
        Core Count: 24
        Core Enabled: 24
        Thread Count: 1
    ...

Big update in the bios-tables-test as it couldn't work with SMBIOS 3.0.

v3:
    * rebase on fresh master
    * crop lines to 80 characters [Igor]
    * add conditions for cc2 field check in the test [Igor]

v2:
    * generate tables type 4 of different sizes based on the
      selected smbios version
    * use SmbiosEntryPoint* types instead of creating new constants
    * refactor smbios_cpu_test [Igor, Ani]
    * clarify signature check [Igor]
    * add comments with specifications and clarification of the structure loop [Ani]
