COMP: Switch Linux/Windows Python Azure CI from MinSizeRel to Release

MinSizeRel (-Os) tests an optimization profile ITK users overwhelmingly
do not ship; users build Release (-O3) or RelWithDebInfo. The historical
reason for MinSizeRel on hosted runners (small artifacts on free-tier
images) no longer applies on current Azure agents.

Switch the surviving Python wrapping jobs to Release so PR signal
matches what users compile. The remaining MinSizeRel canary lives on
the consolidated LinuxLegacyRemovedCxx20 job, which retains coverage
that the unusual optimizer config still builds.

Part of issue #6163 (CI matrix consolidation).
