Add input-output types to $nu.scope.commands (#7105)
* Add input and output types to $nu.scope.commands

This commit changes the schema: instead of

command.signature: table

we now have

command.signatures: list<table>

with one signature for every input-output type pair.

* Represent signatures as a map from input_type to signature

* Sort signature entries

* Drop command name from signature tables

* Don't use "rest" as name of rest parameter; use empty string instead

* Bug fix: was creating records with repeated keys

E.g.
$nu.scope.commands | where name == 'hash sha256' | get signatures.0 | table -e
$nu.scope.commands | where name == 'transpose' | get signatures.0 | table -e
