use new ivar/macro symbol kinds

[QuietMisdreavus]

Bug/issue #, if applicable: rdar://92124246

Summary

This PR uses an in-progress branch of swift-docc-symbolkit that supplies new ivar and macro symbol kinds to provide new curation headings and symbol page kinds for these symbols. The symbol kinds already existed, so this PR merely hooks up the new kinds to the existing work.

Dependencies

swiftlang/swift-docc-symbolkit#30

Testing

As part of a complete toolchain, process an Objective-C symbol graph that includes instance variables and/or macro definitions. Ensure that these symbols correctly appear in the documentation hierarchy and with correct symbol page organization.

Checklist

Make sure you check off the following items. If they cannot be completed, provide a reason.

• Added tests
• Ran the ./bin/test script and it succeeded
• [ n/a ] Updated documentation if necessary

Should we add some test fixtures that include ivars and macros to verify this behavior?

Oh just seeing this:

(help wanted: is there a good place to add tests for this?)

Maybe @d-ronnqvist has ideas but I would start with just adding a minimal symbol graph that includes these types and asserting that the auto-curation works as expected.

[QuietMisdreavus]

I've added a sample symbol graph and a test that makes sure its curation is correct.

@swift-ci Please test

Looks great!

I guess we can land the SymbolKit PR first and re-run CI here since its backwards compatible?

[QuietMisdreavus]

I've updated the PR to point back to SymbolKit's main branch, now that swiftlang/swift-docc-symbolkit#30 has landed.
