@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.
ScreenDimenions - This allows the browser to be called so that it occupies a
portion of the physical screen instead of dynamically determining the screen dimensions.
ActionRequest - Points to the action recommended by the form.
@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_INVALID_PARAMETER One of the parameters has an invalid value.
@retval EFI_NOT_FOUND No valid forms could be found to display.
