Remove lazy records (#12682)

# Description
Removes lazy records from the language, following from the reasons
outlined in #12622. Namely, this should make semantics more clear and
will eliminate concerns regarding maintainability.

# User-Facing Changes
- Breaking change: `lazy make` is removed.
- Breaking change: `describe --collect-lazyrecords` flag is removed.
- `sys` and `debug info` now return regular records.

# After Submitting
- Update nushell book if necessary.
- Explore new `sys` and `debug info` APIs to prevent them from taking
too long (e.g., subcommands or taking an optional column/cell-path
argument).
