Added SWIFT_NAME attributes to all the functions declared in CASTBridging.h

Resolves #68353

Rebase and merge after #67111 has been merged.

@jakedves We merged #67111. If you could you rebase your PR, I’ll take a look at it.

Looks like there’s still some difference between your branch and main because I assume you didn’t modify ASTContext.h.

@ahoppen Hey Alex, I tried to rebase but don't think I got it quite right as there's a lot of changes in this besides CASTBriding.h.

The steps I took:

1. Make my remote fork of apple/swift up-to-date
2. Checkout pr/68492 using GitHub desktop
3. Run git rebase main
4. GitHub desktop then took me through each commit, where I chose "using the modified file" (as opposed to "using the modified file from pr/68492") for all files besides CASTBriding.h (at least I think), and then handled conflicts in that file myself

Is this the right thing to do? It's possible I didn't check properly as GH desktop assumed some resolutions, but want to check the process as I don't have any experience with rebase,

Thanks!

Hmm, I think git gets confused because the ASTGen changes from #67111 are somehow modified. What I would do, is

git checkout add-SWIFT_NAME-attrs
git reset --hard main # Removes all the commits
git cherry-pick 8130dff92784532003976b1897729c550624110e # Adds the commit with your changes to the branch again

@ahoppen I think this is right

Thanks. The commits look good now. You will now need to also make sure the ASTGen module builds with the annotated names. The easiest way to do that, is to open lib/ASTGen and get the package to build.
