Factor out style-setting code (#13406)

Browse Source 
# Description
This is mainly cleanup, but introduces a slight (positive, if anything)
behavior change:

Some menu layouts support only a subset of styles, but with this change
the user will still be able to configure them. This seems strictly
better - if reedline starts supporting one of the existing styles for a
particular layout, there won't be any need to update nushell code.


# User-Facing Changes
None

# Tests + Formatting
This is simply factoring out existing code, old tests should still cover
it.
