Allow merging list policies from different sources

Setting the policy allows merging of selected policies when they come from different sources, with the same scopes and level.

If a policy is in the list and there's conflict between sources with:

* The same scopes and level: The values merge into a new policy list.

* Different scopes or level: The policy with the highest priority applies.

If a policy isn't in the list and there's conflict between sources, scopes, or level, the policy with the highest priority applies.

Example value:

ExtensionInstallAllowlist
ExtensionInstallBlocklist

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
