Add deprecated export file and relocate deprecated code

[jamesmockett]

What are you changing?

• Relocates deprecated code to _deprecated folder and adds exports to deprecated-exports.ts.
• Removes deprecated resets.input styles completely as these are now unused.

Why?

• Having all deprecated code and exports in a single place makes it simpler to remove in the future. deprecated-exports.ts already exists in other packages so this is replicating the same pattern.
