[Libva] [Libva-intel-driver][PATCH v2 03/18] Add some new internal variables for a new sequence

[Xiang, Haihao]

Currently these variables are used only for H.264 encoding

v2: rename frame_width_in_mbs and frame_height_in_mbs to
frame_width_in_pixel and frame_height_in_pixel. It moves
WIDTH_IN_MACROBLOCKS() and HEIGHT_IN_MACROBLOCKS() from gen9_vdenc.h
to i965_encoder.h so that the two macros can be used in
other codecs.
