Label ncondition as callback condition calls (#4058)

`ncondition` counts every callback condition evaluation, discrete included.
Printing it as "rootfind condition calls" makes a solve with only discrete
callbacks look like it is doing continuous-callback rootfinding, which sent a
debugging session down the wrong path.

Covers DiffEqBase's fallback `Stats` show method, used when SciMLBase does not
define `DEStats`, and the DiffEqDevTools work-precision axis label that was
copied from it.
