TextInput v11 Styles

[SimpleProgrammingAU]

Tasks completed and ready for review

• Adopts v11 styles for TextInput and TextInputSkeleton (#1888)
• Addresses FluidForm issues relating to TextInput (#1667)
• Added slots for helperText (#1633), invalidText, warnText (#1621)
• Added elementAttribute objects to replace $$restProps (#1621) - is Record<string, string> the correct type for these?
• Property names checked (#534)

Tasks outstanding

• 752: I think this issue might be better resolved in Select - up for discussion

• 941: I couldn't open the REPL links without errors to see the issue

• 545: I haven't tried to tackle this one yet, will try to address it when I look at the other outstanding tasks above

I also alphabetised the prop list for legibility. I figured this was a good point to submit a PR since all v11 style stuff is done, just need to tidy up the loose ends with the other bugs.

I would recommend doing things that cause a lot of non-functional differences, like sorting properties, in separate PRs. That makes it easier to review as there is less noise.

@brunnerh that's a good tip; I moved this outcome to its own ticket: #1891.

I'll try reviewing this PR as-is for now.

I thought the same thing after the fact. I sorted the properties because I was having so much difficulty finding them in the code as I was reviewing against the React component.

Sorry I submitted my review prematurely. I was using VSCode to review and didn't realize 'request changes' would immediately submit. I'll follow up with the remainder of my review.

Thanks for the feedback. Back to you :)
