WIP: TextKit 2 mk1

[charliescheer]

Fix

This PR is the first step in implementing Textkit 2 into Simplenote. Why do we need this? Well primarily it is to keep up with the next paradigms in apple development. Also with the addition of Textkit 2 we should get all of the new Apple intelligence features for free. Lastly, by removing the reliance on glyphs and glyph ranges in TextKit 2, we should be able to fix many of the out of range crashes that we sometimes see with multi bit character languages.

Here I have taken the first steps. I have:

• created the TextKit 2 layout properties if the device can run them
• layout the text with the same appearance as text in TextKit 1
• allow for tapping into and editing text without switching back to TextKit 1

Test

1. Launch the app, open a note

• Confirm that the text is styled correctly for SN
• Confirm that if you tap into the text you are able to become first responder
• Confirm that you can enter text
• Confirm that you never see this warning in the console UITextView 0x10500fe00 is switching to TextKit 1 compatibility mode because its layoutManager was accessed
