Summary:
iOS should support remapping of modifier keys (Caps Lock, Control, Option, and Command) for all types of hardware keyboards.

This is an important addition to iOS, for ergonomic reasons, as well as accessibility more generally, among other benefits.

Steps to Reproduce:
1. Open Settings app.
2. Navigate to General > Accessibility > Keyboard.

Expected Results:
The user can remap hardware keyboard modifier keys. 

Any hardware keyboard, such as the Smart Keyboard for iPad Pro, but also keyboards connected via Bluetooth, should support the ability to remap modifier keys.

Note that there are already a small number of settings for hardware keyboards, such as Key Repeat, Sticky Keys, and Slow Keys on the General > Accessibility > Keyboard settings screen. This is a natural location to add remapping of modifier keys.

In particular, it should be possible to remap any of the following keys:

- Caps Lock
- Control
- Option
- Command

To any of the following values:

- Caps Lock
- Control
- Option
- Command
- Escape
- Or, alternatively, to no action at all ("No Action").

This mirrors the behaviour of macOS (Accessible via: System Preferences > Keyboard > Keyboard > Modifier Keys).

Observed Results:
The user is unable to remap modifier keys.
