Fix T60132: Convert hair particles to mesh
Needed to port operator to use evaluated particle system.
But also changed interface to always show Convert button when
draw type is set to Path (Hair particle system is forced to
be draws as path). This avoid rather expensive lookup on every
redraw, but will show Convert button for un-baked particle
emitter.
Probably, an acceptable compromise.
