Replace the future flag for multiple policies II

Using 'future_on' instead of 'future' flag for the following policies:
CrostiniArcAdbSideloadingAllowed
CrostiniExportImportUIAllowed
DeviceCrostiniArcAdbSideloadingAllowed

Except the DeviceCrostiniArcAdbSideloadingAllowed, all policies will be
filtered out in Beta and Stable.

The follwing policies are actually launched, removing the future flag
for them.
CrostiniAnsiblePlaybook
FloatingAccessibilityMenuEnabled
VirtualKeyboardFeatures
PluginVmDataCollectionAllowed

BYPASS_POLICY_COMPATIBILITY_CHECK=Four policies are launched few milestones
ago without removing the future flag.
