Use correct beamspot for 2016 MC + update MC tracker alignment scenario for 2016 pre-VFP era [10_6_X]

[christopheralanwest]

PR description:

This PR is a backport of PR #28624, which changes the default beamspot for 2016 scenarios and updates the tracker APEs for MC of the 2016 pre-VFP era. Commits 5d50378 and
e514a31 are cherry-picked from the PR to master. The 10_6_X branch requires an additional two changes of the beamspot scenario, in commit 662b68c. Finally, the global tags are updated in commit 5ea966a. The changes to the GTs can be understood by comparing the diffs with respect to the previous 10_6_X autoCond GTs or by comparison with those in master.

Comparison with previous 10_6_X GT

2016 design MC
Updated to use ideal beamspot

2016 preVFP pp collision MC
Updated to use 25ns beamspot rather than 50ns beamspot. Update to tracker APEs

2016 cosmic MC
Updated to use 25ns beamspot rather than 50ns beamspot. Not relevant but change is made to minimize unnecessary differences between cosmic and pp collision GTs

sorry I thought I have already signed

[cmsbuild]

This pull request is fully signed and it will be integrated in one of the next CMSSW_10_6_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_11_1_X is complete. This pull request will now be reviewed by the release team before it's merged. @davidlange6, @silviodonato, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
