GHA: bump some jobs to ubuntu-26.04

In jobs that may benefit from newer tool versions (pyspelling, possibly
CodeQL, CM integration, configure-vs-cmake). Also curl-for-win to match
the curl/curl-for-win repo that also bumped. Bump some Linux jobs to add
variation. Also the rest of `check*` jobs for no particular reason other
than using the latest.

Follow-up to 8f5e4f020e #22097
Follow-up to 139ce4d37c #22096
Follow-up to e44f1a1446 #22094

Closes #22092
