The new method is a wrapper of `CXXMethodDecl::isCopyAssignmentOperator` and can be used to recognized copy-assignment operators in libclang. An export for the method, together with its documentation, was added to "clang/include/clang-c/Index.h" with an implementation provided in "clang/tools/libclang/CIndex.cpp". The implementation was based on similar `clang_CXXMethod.*` implementations, following the same structure but calling `CXXMethodDecl::isCopyAssignmentOperator` for its main logic. The new symbol was further added to "clang/tools/libclang/libclang.map" to be exported, under the LLVM16 tag. "clang/tools/c-index-test/c-index-test.c" was modified to print a specific tag, "(copy-assignment operator)", for cursors that are recognized by `clang_CXXMethod_isCopyAssignmentOperator`. A new regression test file, "clang/test/Index/copy-assignment-operator.cpp", was added to ensure that the correct constructs were recognized or not by the new function. The "clang/test/Index/get-cursor.cpp" regression test file was updated as it was affected by the new "(copy-assignment operator)" tag. A binding for the new function was added to libclang's python's bindings, in "clang/bindings/python/clang/cindex.py", adding a new method for `Cursor`, `is_copy_assignment_operator_method`. The current release note, `clang/docs/ReleaseNotes.rst`, was modified to report the new addition under the "libclang" section.
