lottie: introduced static layer cache.
...
lottie builder doesn't need to rebuild the layer object
if it has no any animation frame data.
That case, we can cache the layer scene in order to reuse it.
Tested on local machine (single thread):

lottie/builder: Fix overlapped stroking outlines.
...
Previously, the builder accumulated the outlines and fills
in one paint to reduce the rendering context.
However, this approach won't work for Lottie
if the resource contains multiple strokes with branched groups.
We should apply the optimization
only when the specified condition is satisfied.

Rounded corners should now be applied not only to rectangles

to round when a rounded corner is present.
Indeed, rounded corners ensure the accurate calculation of roundness based on the join style.
