SkWebpCodec: enable a loop count of 1

Commit 557fbb added animation support to SkWebpCodec, with the intent to
match Chromium. This was during the ~1.5 year period between
crbug.com/592735 and crbug.com/649264 when Chromium attempted to align
WebP with GIF, and play the animation once more than the stored number
(see crbug.com/592735). This was later reverted, because it means that a
WebP is unable to play an animation a single time (see
crbug.com/649264). This commit catches SkWebpCodec up with Chromium.

Add a legacy build flag (SK_LEGACY_WEBP_LOOP_COUNT) so we can stage the
change on Android.
