COMP: Drop redundant non-Python Windows and macOS Azure CI lanes

A Python-wrapping build is a strict superset of the same OS+arch
non-Python build. AzurePipelinesWindows and AzurePipelinesMacOS were
duplicating coverage already provided by AzurePipelinesWindowsPython
and AzurePipelinesMacOSPython respectively.

Move BUILD_SHARED_LIBS=ON onto the macOS Python lane so the macOS
shared-library build coverage previously carried by AzurePipelinesMacOS
is preserved on the surviving job. Bump that job's Python to 3.12 to
stagger Python-version coverage across surviving Python lanes.

Part of issue #6163 (CI matrix consolidation).
