[CI] Run the nightly legs from their own jobs

jobs.<id>.if cannot read matrix, so the previous filter never validated and
no leg of this workflow ran. matrix.exclude cannot express it either: GitHub
processes exclude before include, and these matrices are include-only.

Split the regular and nightly legs into two jobs per platform, sharing the
step list through a YAML anchor and gating the jobs on the event instead of
on matrix. The nightly run now covers only the legs a push leaves out, and
the event name is part of the concurrency group so a nightly and a master
push do not cancel each other.
