 /**
   Initialize the browser to display the specified configuration forms.

   This function is the primary interface to the internal forms-based browser.
   The forms browser will display forms associated with the specified Handles.
   The browser will select all forms in packages which have the specified Type
   and (for EFI_HII_PACKAGE_TYPE_GUID) the specified PackageGuid.

   @param This            A pointer to the EFI_FORM_BROWSER2_PROTOCOL instance

   @param Handles         A pointer to an array of Handles. This value should correspond
                          to the value of the HII form package that is required to be displayed.

   @param HandleCount     The number of Handles specified in Handle.

   @param FormSetGuid     This field points to the EFI_GUID which must match the Guid field or one of the
                          elements of the ClassId field  in the EFI_IFR_FORM_SET op-code.  If
                          FormsetGuid is NULL, then this function will display the form set class
                          EFI_HII_PLATFORM_SETUP_FORMSET_GUID.

   @param FormId          This field specifies the identifier of the form within the form set to render as the first
                          displayable page. If this field has a value of 0x0000, then the Forms Browser will
                          render the first enabled form in the form set.

   @param ScreenDimensions Points to recommended form dimensions, including any non-content area, in
                           characters.

   @param ActionRequest   Points to the action recommended by the form.

   @retval EFI_SUCCESS           The function completed successfully

   @retval EFI_NOT_FOUND         The variable was not found.

   @retval EFI_INVALID_PARAMETER One of the parameters has an
                                 invalid value.
