feat(ast): accept arrays for ArenaVec params of AST builder methods (#24621)

Builds on #24620.

Make generated and hand-written AST builder methods take `impl IntoIn<'a, ArenaVec<'a, T>>` instead of `ArenaVec<'a, T>` for their `Vec` params, so callers can pass an array literal (e.g. `[]` or `[a, b]`) in place of building an `ArenaVec` explicitly.

This enables shortening code in a lot of places - #24622 and following PRs.
