Extract pub const NAME for all array encoding structs

[jiaqizho]

Summary

Add a pub const NAME: &str to every array encoding struct and derive pub const ID: ArrayId from Self::NAME instead of an inline string literal. This eliminates duplicated encoding name strings and gives external code a stable constant to reference when matching on encoding IDs.

I'm not sure I understand the goal here? Why is there duplicate strings in the existing world but not in the new world?

Was there a reason for this change in relation to #6974?

I think I still personally like this change but the reasoning isn't super clear here, where are the duplicated strings in the current codebase?

Yes, after refactoring the implementation from #6974, this change is no longer needed, so closed.
