* Move `PalletVersion` away from the crate version
Before this pr, `PalletVersion` was referring to the crate version that
hosted the pallet. This pr introduces a custom `package.metadata.frame`
section in the `Cargo.toml` that can contain a `pallet-version` key
value pair. While the value is expected to be a valid u16. If this
key/value pair isn't given, the version is set to 1.
It also changes the `PalletVersion` declaration. We now only have one
`u16` that represents the version. Not a major/minor/patch version. As
the old `PalletVersion` was starting with the `u16` major, decoding the
old values will work.
* Overhaul the entire implementation
- Drop PalletVersion
- Introduce StorageVersion
- StorageVersion needs to be set in the crate and set for the macros
- Added migration
* Fix migrations
* Review feedback
* Remove unneeded dep
* remove pub consts
* Brings back logging and implements `GetStorageVersion`
* Return weight from migration
* Fmt and remove unused import
* Update frame/support/src/dispatch.rs
