Use mixed bitmap between FrameEncoder and FrameFilter to Fix crash and hash mistake in WPP mode

I change task schedult bitmap to mixed FrameEncoder and FrameFilter
because there catch two bugs, and I want to reduce latency of Frame
Parallelism.
The new bitmap mapping 2N+0 to FrameEncoder and 2N+1 to FrameFilter.

Side effect:
1. We can remove the lock from FrameFilter.
2. Mixed bitmap let us do Filter early, so reduce latency of Frame
   Parallelism

Solved bugs:
1. CRASH: the reason is sometime two of threads finish in same time,
   so they will enter Filter in wrong order and sent Finished Event
   early.
   when main thread dequeue JobProvider and execute FrameFilter, we
   will catch a crash!

2. HASH MISTAKE: the reason is same as below, but last row is right
   order, we will got worng reconst image.
