/** Entrypoint of Dynamic Table Manager Dxe.

  The Dynamic Table Manager uses the Configuration Manager Protocol
  to get the list of ACPI and SMBIOS tables to install. For each table
  in the list it requests the corresponding ACPI/SMBIOS table factory for
  a generator capable of building the ACPI/SMBIOS table.
  If a suitable table generator is found, it invokes the generator interface
  to build the table. The Dynamic Table Manager then installs the
  table and invokes another generator interface to free any resources
  allocated for building the table.

  @param  ImageHandle
  @param  SystemTable

  @retval EFI_SUCCESS           Success.
  @retval EFI_OUT_OF_RESOURCES  Memory allocation failed.
  @retval EFI_NOT_FOUND         Required interface/object was not found.
  @retval EFI_INVALID_PARAMETER Some parameter is incorrect/invalid.
