New "format corner" icons

[shajz]

These rotated versions of icon-formatCornerUpLeft and icon-formatCornerUpRight are not available in LF

I get by for now with this bit of scss (in a dropdown), but it would be nice to have them available

.lu-dropdown-options-item-action {
  .lucca-icon.icon-formatCornerUpLeft {
    transform: rotate(90deg);
  }
  .lucca-icon.icon-formatCornerUpRight {
    transform: rotate(90deg);
  }
}
