Encoder: HEVC: Add more tuning options

Submitted by Sreerenj Balachandran @sree

Link to original bug (#749853)

Description

The va-intel-driver is not supporting all encoding tools, but still we can add a couple of features to enable High Compression Tuning option.

-- Enable B-frames for High Compression

-- Current implementation is Using 32x32 CTU by default. Use 16x16 mode as default and Change it to 32x32 or 64x64 based on tuning options.
BTW, 64x64 is not yet supported by the driver.

-- Add support for B-frame Reference Picture Encoding.
