ematejska fbec91a1b5 [Autodiff] Derivative Registration for the Get and Set Accessors (#32614) 
* initial changes

* Add tests, undo unnecessary changes.

* Fixing up computed properties accessors and adding tests for getters.

* Adding nested type testcase

* Fixing error message for when accessor is referenced but not acutally found.

* Cleanup.

- Improve diagnostic message.
- Clean up code and tests.
- Delete unrelated nested type `@derivative` attribute tests.

* Temporarily disable class subscript setter derivative registration test.

Blocked by SR-13096.

* Adding libsyntax integration and fixing up an error message.

* Added a helper function for checking if the next token is an accessor label.

* Update utils/gyb_syntax_support/AttributeNodes.py

Co-authored-by: Dan Zheng <danielzheng@google.com>

* Update lib/Parse/ParseDecl.cpp

Co-authored-by: Dan Zheng <danielzheng@google.com>

* Add end-to-end derivative registration tests.

* NFC: run `git clang-format`.

* NFC: clean up formatting.

Re-apply `git clang-format`.

* Clarify parsing ambiguity FIXME comments.

* Adding couple of more testcases and fixing up error message for when accessor is not found on functions resolved.

* Update lib/Sema/TypeCheckAttr.cpp
