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. Type
@param HandleCount The number of Handles specified in Handle.
@param FormSetGuid This field points to the EFI_GUID which must match the Guid
field in the EFI_IFR_FORM_SET op-code for the specified
forms-based package. If FormSetGuid is NULL, then this
function will display the first found forms package.
@param FormId This field specifies which EFI_IFR_FORM to render as the first
displayable page. If this field has a value of 0x0000, then
the forms browser will render the specified forms in their encoded order.
@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.
