Bug 562096 - Switch CDT 10.0 stream to Eclipse Platform 4.16 M1

Switched to
https://download.eclipse.org/eclipse/updates/4.16milestones/S-4.16M1-202004090200/
Added 2020-06 repository list to CDT.setup - let's keep 2020-03 for a
while as a fallback option until things are converged for 2020-06 stream
