feat: allow cycling through multiline commands using up/down in the REPL

[Snehil-Shah]

Resolves #2070

Description

What is the purpose of this pull request?

This pull request:

• adds support for cycling through whole commands using up/down arrow keys

Behaviors:

• Line before the cursor is used as prefix to filter out the history.
• Once a traversal has started, the user is cycling for that particular prefix (that started the traversal) as long as only up and down arrows are used.
• If any other key is used in the middle of a traversal, the traversal is reset as the user might be trying to change the prefix used or just wants to start traversing from zero again.
