lavc/vaapi_encode: add EQUAL_MULTI_ROWS support for slice structure

Browse Source 
VA_ENC_SLICE_STRUCTURE_EQUAL_MULTI_ROWS is added to in the latest
libva (1.8.0) which matches the hardware behaviour:

/** \brief Driver supports any number of rows per slice but they must
*    be the same for all slices except for the last one, which must be
*    equal or smaller to the previous slices.
*/

And VA_ENC_SLICE_STRUCTURE_EQUAL_ROWS is kind of deprecated for iHD
since it's somehow introduced in [1] which is misleading from what we
actually handles.
