[PATCH v3 2/3] hw/smbios: Use qapi for SmbiosEntryPointType

[Eduardo Habkost <ehabkost@redhat.com>]

This prepares for exposing the SMBIOS entry point type as a
machine property on x86.

Based on a patch from Daniel P. Berrangé.

First version of this code was submitted at:
https://lore.kernel.org/qemu-devel/20200908165438.1008942-5-berrange@redhat.com

Changes from v2:
* Rename "2_0"/"3_1" to "32"/"64", to
  make the names more QAPI-friendly (as underscores and dots are
  not allowed by QAPI)
* Move definition from smbios.json back to machine.json
  (no need for a separate file just for one enum)

Changes from v1:
* Patch was split in two
* Moved definition to smbios.json
