bb4fc051bf gif2webp: Allow single-frame animations 
Some single-frame GIF images have a canvas larger than the frame rectangle. For
such images, we retain the ANMF, ANIM and VP8X chunks in the output WebP file.
This ensures that the full canvas width/height and frame offsets are retained.

46fd44c104 thread: remove harmless race on status_ in End() 
if a thread was still doing work when End() was called there'd be a race
on worker->status_. in these cases, however, the specific value is
meaningless as it would be >= OK and the thread would have been shut
down properly, but we'll check 'impl_' instead to avoid any potential
TSan/DRD reports.

6422e683af VP8LFillBitWindow: enable fast path for 32-bit builds 
also reduce the load size from 64 to 32 bits as the top 32 bits are
being shifted away in the operation.

the change is neutral speed-wise on x86_64 as is the change in load size
on x86, but it gives a slight improvement on 32-bit arm.
x86 is improved ~13%, 32-bit arm ~3.7%
aarch64 is untested but will likely benefit as well.

4536e7c49c add WebPMuxSetCanvasSize() to the mux API 
previously, the final canvas size was adjusted tightly from the
animation frames. Now, it can be specified separately (to be larger, in particular).

calling WebPMuxSetCanvasSize(mux, 0, 0) triggers the 'adjust tightly' behaviour.
This can be useful after calling WebPMuxCreate() if further image addition
is expected.

-> Fixed gif2webp accordingly.

also: made WebPMuxAssemble() more robust by systematically zero-ing WebPData.
