Revert "elm/win: move trigger for "shot" to first pre-render callback"

Summary:
This reverts commit 93228108efaf6097ac680664bdb9158b5cf57499.

The original commit resulted in a hang during the use of the shot engine
in our make doc target. During the doc run we generate screenshots for
the documentation using the shot engine.

It is not a clean revert as other things changed since this got in, but
I verified that the screenshots for the documentation is generated
correctly again. This might leave open the original issue T6929 which
the now reverted commit tried to address.

Fixes T7166
