If we want to add font styling to display a string that has lower case letters as upper case, there doesn't appear to be an option for that any more.

Currently we have `kLowerCaseType` but that only has small or petite caps.

There is also the `String` function `uppercased()` but that changes the string value.

There use to be `kLetterCaseType` and `kAllCapsSelector` but its deprecated.

It would be ideal to add a `kLowerCaseAllCapsSelector` to `kLowerCaseType`.
This might also need a `kUpperCaseNoCapsSelector` for `kUpperCaseType` but this is not the subject for this Suggestion.

Steps to Reproduce:
Create an attributed string
Use UIFontDescriptor to set the font style
Notice no option for all-caps

Expected Results:
A `kLowerCaseType` selector for all-caps

Observed Results:
There use to be `kLetterCaseType` and `kAllCapsSelector` but its deprecated. There may be a regression to lose an all-caps option.

Casing operations have many edge cases and should be performed on strings, not glyphs.
