refactor(lsp): flat_map with mutable accumulator (#15567)
# Description

Mainly performance improvement of lsp operations involving flat_map on
AST nodes.
Previous flat_map traversing is functional, which is a nice property to
have, but the heavy cost of vector collection on each tree node makes it
undesirable.

This PR mitigates the problem with a mutable accumulator.

nu-protocol

The nu-protocol crate holds the definitions of structs/traits that are used throughout Nushell. This gives us one way to expose them to many other crates, as well as make these definitions available to each other, without causing mutually recursive dependencies.
