Bug 1633855 - Re-work the experimental definitions for features; r=julienw

This commit changes up the definitions of the presets a bit. I promoted the
allocations work to non-experimental, as it's fairly well supported now in the UI.
Others I demoted to experimental if they were not supported in our current UI,
or flat out don't work.
