Lazily create the Path in StylePath

Lazily create the Path in StylePath

Instead of creating the Path object up front - when the StylePath is
created - create it on first access/use (usually on paint/layout.)

Pondered this while looking at 'd' property perf regression. I don't that it'll
be a big win in the common cases, but when 'd' becomes so hip (as I'm sure it
will be) this might save a few Paths worth when it applies where it's not used.

Gain ~ Uglyness

¯\_(ツ)_/¯
