avcodec/mpegvideo_enc: Don't use unnecessarily much stack

encode_thread() puts two MPVEncContexts (2*6516B here)
on the stack and zeroes one of them in order to
temporarily store the variables that get changed
during encoding a macroblock (when there is more than
one candidate type for a macroblock). This is wasteful
and therefore this commit adds a small (328B here) structure
to store exactly the fields that actually need to be backed
up. Then one can extend MPVEncContext without fearing
too use up to much stack.
