ci: replace macOS 10.15 with macOS 11 in CI pipelines (#717)

* ci: replace macOS 10.15 with macOS 11 in CI workflow

GitHub started the deprecation process for macOS 10.15 runners
on 2022-05-31, and macOS 10.15 will be completely unsupported by
2022-08-30 (if things proceed as planned).

See <https://github.com/actions/runner-images/issues/5583> for
more information on the removal of the macOS 10.15 images.

This issue already hit us during the build for PR #716, because
at that time there was a scheduled brownout for macOS 10.15
builds to raise awareness of the upcoming removal.

* ci: remove Azure pipeline build configuration

See <https://github.com/boostorg/gil/pull/717#issuecomment-1212415021>.
