Subject: Rename GPUParticles2D/3D's `trail_length_secs` to `trail_lifetime`

The property already has a "seconds" suffix in the inspector.
The "lifetime" term makes it more obvious that the property is
specified as time, not a distance in units.

The property hint now allows manually entering values greater than
10 seconds.

The internal rendering value's default now matches the particles
nodes' default.
