Refactor config updates (#13802)
# Description
This PR standardizes updates to the config through a new
`UpdateFromValue` trait. For now, this trait is private in case we need
to make changes to it.

Note that this PR adds some additional `ShellError` cases to create
standard error messages for config errors. A follow-up PR will move
usages of the old error cases to these new ones. This PR also uses
`Type::custom` in lots of places (e.g., for string enums). Not sure if
this is something we want to encourage.

# User-Facing Changes
Should be none.
