[Types] spring-split

[keithharvey]

Part of BAR type-error cleanup. Rebuilds idempotently from master via just bar::fmt-mig-generate.

# spring-split - split Spring into SpringSynced, SpringUnsynced, and SpringShared
bar-lua-codemod spring-split --path "$BAR_DIR" --library "$BAR_DIR/recoil-lua-library/src" --exclude common/luaUtilities

See RecoilEngine#2799 for the SpringSynced/SpringUnsynced/SpringShared type split on the engine side.
