Make Controlling Mixin only load if Controlling is installed

[BlayTheNinth]

Minecraft Version

1.21.11

Mod Loader

NeoForge / Fabric / Forge

Describe the Issue

Right now if Controlling is not installed it leads to this error message in the log:

[15:48:02] [main/WARN]: Error loading class: com/blamejared/controlling/client/NewKeyBindsList$KeyEntry (java.lang.ClassNotFoundException: com/blamejared/controlling/client/NewKeyBindsList$KeyEntry)
[15:48:02] [main/WARN]: @Mixin target com.blamejared.controlling.client.NewKeyBindsList$KeyEntry was not found kuma_api.mixins.json:controlling.ControllingKeyEntryMixin from mod kuma_api

It's harmless, but may lead users to make reports or incorrectly attribute errors to Kuma/Balm.

Initial attempt at adding a Mixin Plugin to make it conditional lead to weird class mismatches (possibly due to different Mixin versions/flavors in the subprojects?)... we'll have to see.
