Edit Comment: add initial view

[ScoutHarris]

Ref: #17000

This adds an initial new Edit Comment view.

• It has sections for each editable field.
• The actual fields are empty and not editable yet.
• The nav bar Cancel and Done buttons simply dismiss the view for now.
• Display is controlled by the newCommentEdit feature flag, which is disabled by default.

To test:

---

With newCommentEdit enabled:

• Go to My Site > Comments > Comment details > Edit.
  • Verify the new edit view is displayed.
• Go to Notifications > Comments > Notification details > Edit.
  • Verify the new edit view is displayed.

iPhone	iPad

---

With newCommentEdit disabled:

• Go to My Site > Comments > Comment details > Edit.
  • Verify the existing edit view is displayed.
• Go to Notifications > Comments > Notification details > Edit.
  • Verify the existing edit view is displayed.

PR submission checklist:

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.

Hey @mattmiklic . I wasn't sure if the new Edit Comment view should be a modal or not. The old one is, and I think that works well, at least on iPad. So I left it that way. But let me know if you think otherwise.

Yep, that's correct. In the designs I'd mocked it up as a fullscreen modal rather than a sheet, but there's functionally not a big difference and this should be fine.

Thanks @mattmiklic .

Yea, I totally didn't get fullscreen vs sheet 🤦. Sorry! I'll make that change in the next PR.

No problem; thanks!

Since @dvdchr hasn't reviewed this yet, I went ahead and updated it to show the new edit view in a full screen modal. Note the nav bar background matches what the app uses, not what's in Zeplin.

Tested on iPhone and iPad. Everything looks good! 👍
