Migrate pallet-state-trie-migration to umbrella crate

Part of #6504

Sorry for bothering you about this @re-gius , this miight be a dumb question but :
I have this defensive! macro which is from frame_support, how can i get it to work with the umbrella crate since the macro uses frame_support inside of itself ? I have tried to add the defensive! macro to the prelude but it doesnt work since the inside of the macro calls for frame_support (https://paritytech.github.io/polkadot-sdk/master/src/frame_support/traits/misc.rs.html#67-95)

Sorry for the late reply. The macro generates code containing frame_support, so there's no way to solve this for now. We should also avoid changing the macro code, since it may be called in places where the umbrella crate is not available. We could generate a copy of the defensive macro in the umbrella crate and use that here, but this may cause conflicting names somewhere in the codebase.
