Cycles: Schedule more samples to path trace work

The new scheduling goes as following:

- Render 1 sample, give visual feedback, and see how long it takes to
render a sample.

- After that schedule as many samples as needed to not have more frequent
updates then once a second.

Currently there are no measurable difference, but it will become more
visible once we'll be scheduling more than one sample to GPU.

Cycles: Implement special path trace work for CPU

Uses tbb's parallel_for to do pixel partitioning, avoiding overhead
of per-pixel atomic.

Brings render time of bmw27 from 2:19 to 2:10 (2.92 renders in 2:01).

Cycles: Move tiled path tracer work to own class

The goal is to abstract things a bit and make it possible to tap
more CPU-friendly scheduler to the path tracer.

No functional changes are expecting.
