Disable pipeline echo (#8292)
# Description

Change behavior of block evaluation to not print result of intermediate
commands.
Previously result of every but last pipeline in a block was printed to
stdout, and last one was returned

With this change results of intermediate pipelines are discarded after
they finish and the last one is returned as before:

Now one should use `print` explicitly to print something to stdout

**Note, that this behavior is not limited to functions!** The scope of
this change are all blocks. All of the below are executed as blocks and
thus exibited this behavior in the same way:

With this change outputs for all types of blocks are cleaned:

# User-Facing Changes

All types of blocks (function bodies, closures, `if` branches, `for` and
`loop` bodies e.t.c.) no longer print result of intermediate pipelines.

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

# After Submitting

If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
