[mpp_enc_cfg]: Add encoder I frame tuning config

Browse Source 
Add max_i_prop, min_i_prop and init_ip_ration for I frame tuning config.

max_i_prop:
The max percentage of intra frame size in one gop.

min_i_prop:
The min percentage of intra frame size in one gop.

init_ip_ration:
Define the first I frame size is how many times of one P frame size.
Set to 16 mean I frame size is equal to P frame size.
Set to 160 mean I frame size is 10 times of P frame size.

These three parameters are for tuning Intra frame quality.
