Series hw/smbios: add core_count2 to smbios table type 4 | expand

Commit Message

Julia Suvorova Oct. 11, 2022, 11:17 a.m. UTC 
The new test is run with a large number of cpus and checks if the
core_count field in smbios_cpu_test (structure type 4) is correct.

Choose q35 as it allows to run with -smp > 255.
