Some SMBIOS tables have dependencies on other SMBIOS tables. These
dependencies are established using handles pointing to the dependent
SMBIOS tables.
This requires the dependent SMBIOS table to be installed before the
parent SMBIOS table can be installed.
To facilitate dynamic SMBIOS table generation, a SMBIOS table
dispatcher has been introduced. The SMBIOS table dispatcher
schedules the installation of dependent SMBIOS tables before
the parent SMBIOS table is installed.
The changes can be seen at:

These dependencies are established using handles pointing to the dependent tables. A SMBIOS table handle can be obtained by either installing a SMBIOS table or by allocating a handle, which requires complex management to avoid any clashes. Obtaining a SMBIOS handle by installation requires that the dependent table is installed before the parent SMBIOS table can be installed. Therefore, introduce a SMBIOS table dispatcher that walks the SMBIOS dependency list and schedules the dependent tables to be installed before the parent table is installed.
