Enforce Text suffix for Text-rendering components

[gaearon]

Follow-up to #3398.

This renames a bunch of components that always "promise" to render Text:

• Description -> DescriptionText
• InlineLink -> InlineLinkText
• Label -> LabelText
• Suffix -> SuffixText

It's not super "pretty" but it very clearly communicates the expectations that they render Text.

I've left H1..H7 and P "as is" because they're obviously text.

The last commit adds a lint rule check that enforces that such components always return Text.

That's to prevent regressions.

This doesn't address buttons which I'll need to take a pass on separately.

Test Plan

Did this via IDE renames (TS language server). Walked around the app too.

Nice — honestly would be cool to pull this out in the future so 3rd parties can include in their RN projects, such a footgun and easy to miss

@estrattonbailey Not needed in this PR, but are we planning on using H1-7 at all? Can we rm if not? I think we decided not to but idr for sure.
