[EPIC] [SDK] Support pathData (addPath/addPathNodes) in icon generation

[egorikftp]

Currently, we generate icon path in following format:

path(fill = SolidColor(Color.White)) {
    moveTo(30f, 60f)
    curveTo(46.569f, 60f, 60f, 46.569f, 60f, 30f)
    close()
}

We can provide new format for path. Instead function call we can define path as string

addPath(
    fill = SolidColor(Color(0xFFFFFFFF)),
    pathData = addPathNodes("M 30 60 C 46.569 60 60 46.569 60 30 Z"),
)

Note: This will be less optimal because the icon path will be parsed before rendering.
