Add `isResourceProtected`

[xLive]

Describe the bug

We know you can protect your resources by active protected flag in mtaserver.conf
so admins/mods cannot stop/restart it via stop/restart command,
but you can with stopResource,restartResource functions
so admins/mods can stop it by resources like admin panel or other moderation resources
To reproduce

1. open admin panel
2. stop/restart a protected resource

Expected behaviour
stopResource,restartResource
mustn't stop/restart the resource because is protected
Version
MTA:SA Server v1.5.7-release-18957
Additional context
I have two ideas to solve the problem

1. if the resource is protected stopResource,restartResource functions should return false
   or 2. Add isResourceProtected function to prevent moderation resources from stop/restart protected resources

Second is a better idea than first imho

Just wondering why this issue has moved to mta-resources,
We can't fix it in Lua because we can't know if the resource is protected or not? @qaisjp

I misread your additional context suggestion number two. I thought that function already existed. I will move it back.
