Mark API from 7 as shipped

Took all of the .shipped files from #46042, built the repo, and fixed errors one-by-one.

I checked git diff wtgodbe:wtgodbe/Api7..wtgodbe:wtgodbe/Api8 -- **/PublicApi.Shipped.txt and got no output. Am I correct you haven't (yet) had to update the Shipped files for nullability reasons❔

But, from the CI errors, it looks like some symbols are missing from the Unshipped files still…

I also get the same lack of output from ... -- **/PublicApi.Unshipped.txt. Since the wtgodbe/Api7 Unshipped files are empty (I checked), are the right files in wtgodbe/Api8❔

Correct, I didn't encounter any instances where I'd have to do this. Which makes sense, if those nullability changes should never have been in Unshipped in the first place, this PR wouldn't have to touch them (if they're already in Shipped, they'll stay there)

Argh, yep, something's wrong. Weird, it passed for me locally. Will take a look.

Something's up there, there's definitely differences - e.g.:

https://github.com/wtgodbe/aspnetcore/blob/wtgodbe/Api7/src/Components/Components/src/PublicAPI.Unshipped.txt
https://github.com/wtgodbe/aspnetcore/blob/wtgodbe/Api8/src/Components/Components/src/PublicAPI.Unshipped.txt

Seems to working for me now locally

I've spot-checked some of the changes. Thanks @wtgodbe !

Checked a few things locally:

1. Very few (7) Shipped files differ from what's now in release/7.0. The differences relate to
2. Renaming for the net7.0 -> net8.0 transition
3. Slight ordering changes in renamed files
4. Newly-nullable public surface
5. The new src/Servers/Kestrel/Transport.NamedPipes/src/ project
6. 24 Unshipped files contain various changes. Most seem to be removals or small additions. That's fine as long as the CI agrees.

Only failure is the expected one in Code Check - merging
