LibVideo/VP9: Don't store the default_intra_mode in a field

Browse source 
The default intra prediction mode was only used to set the sub-block
modes and the y prediction mode. Instead of storing it in a field, with
the sub modes are stored in an Array, we can just pull the last element
to set the y mode.
