Be more careful to not create ticks earlier than needed, as that's quite
costly.

On the following benchmark

from matplotlib import pyplot as pltfrom time import perf_counterfig = plt.figure()for i in range(3):    print(i)    start = perf_counter()    fig.subplots(10, 10)    print(perf_counter() - start)  # creation time    start = perf_counter()    fig.clf()    print(perf_counter() - start)  # clearance time

this speeds up axes creation from ~1.4s to ~0.5s and figure clearance(!)
from ~2.6s to ~0.3s.

Note that a similar idea was already implemented inc935965, which sped
up creation from ~2.6s to 0.8s and clearance from ~2.2s to ~1.8s, but
obviously the whole thing is brittle and got mostly lost at some
point...

Would be nice to track performance regressions (semi)automatically.

attn@timhoffm as you initially had this idea in#9727

(#16066 made this a bit more of a pain than expected)

edit: hmmm, looks like this just transfers the cost to draw time, will investigate more...
