v5: Floating labels (#30449)

* v5: Promote floating labels example to component

- Adds new .form-floating
- Stubs out basics of a docs page
- Removes existing Example

* Update floating labels to support .form-select, make inputs and selects more consistent

- To do this, I made the .form-control and .form-select consistent in min-height vs height
- Removed some unused variables now
- Updated -color to be the -color because I don't know why this was any different before
- Update page to include some examples for layout, validation, and value
- Rewrite styles to not modify padding, but instead transform and opacity

* Streamline and bulletproof some things

- Apply some optimizations from code review
- Removed unecessary properties from the label
- Add some comments for what properties are required
- Move from fixed height for labels to height 100% so we can support textareas
- Improve docs a little bit, add ToC

* Move some values to variables, switch from scaling font-size to scale, update transforms

* Bring over changes from #30966 and add to them to tighten things up

* Delete the now unused example images

* Fix typo

* Allowlist the calc function

* Add transform-origin, update transform values

* Test out autofill fix

* Fix linter issue

* Mention it in the migration guide

* Bump bundlesize

* Add one more variable per review

* Shave .25rem off the height
