Make length only operate on supported input types (#14475)
# Description


Before this PR, `length` did not check its input type at run-time, so it
would attempt to calculate a length for any input with indeterminate
type (e.g., `echo` which has an `any` output type). This PR makes
`length` only work on the types specifically supported in its
input/output types (list/table, binary, and nothing), making the
behavior the same at parse-time and at run-time.

Fixes #14462

# User-Facing Changes


Length will error if passed an unsupported type:

Before (only caught at parse-time):
```nushell
"hello" | length
Error: nu::parser::input_type_mismatch

  × Command does not support string input.
   ╭─[entry #2:1:11]
 1 │ "hello" | length
   ·           ───┬──
   ·              ╰── command doesn't support string input
   ╰────

echo "hello" | length
# => 1
```

After (caught at parse-time and run-time):
```nushell
"hello" | length
Error: nu::parser::input_type_mismatch

  × Command does not support string input.
   ╭─[entry #22:1:11]
 1 │ "hello" | length
   ·           ───┬──
   ·              ╰── command doesn't support string input
   ╰────

echo "hello" | length
Error: nu:🐚:only_supports_this_input_type

  × Input type not supported.
   ╭─[entry #23:1:6]
 1 │ echo "hello" | length
   ·      ───┬───   ───┬──
   ·         │         ╰── only list, table, binary, and nothing input data is supported
   ·         ╰── input type: string
   ╰────

Nushell core libraries and plugins

These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.

Foundational libraries are split into two kinds of crates:

  • Core crates - those crates that work together to build the Nushell language engine
  • Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.

Plugins are likewise also split into two types:

  • Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
  • Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
