KCL: Angled line should use keyword args (#5803)

We continue migrating KCL stdlib functions to use keyword arguments. Next up is the `angledLine` family of functions (except `angledLineThatIntersects, which will be a quick follow-up).

Before vs. after:

`angledLine({angle = 90, length = 3}, %, $edge)`
  => `angledLine(angle = 90, length = 3, tag = $edge)`

`angledLineOfXLength({angle = 90, length = 3}, %, $edge)`
  => `angledLine(angle = 90, lengthX = 3, tag = $edge)`

`angledLineOfYLength({angle = 90, length = 3}, %, $edge)`
  => `angledLine(angle = 90, lengthY = 3, tag = $edge)`

`angledLineToX({angle = 90, length = 3}, %, $edge)`
  => `angledLine(angle = 90, endAbsoluteX = 3, tag = $edge)`

`angledLineToY({angle = 90, length = 3}, %, $edge)`
  => `angledLine(angle = 90, endAbsoluteY = 3, tag = $edge)`
