The new method is a wrapper of `CXXConstructorDecl::isExplicit` and `CXXConversionDecl::isExplicit`, allowing the user to recognize whether the declaration pointed to by a cursor was marked with the explicit specifier. An export for the function, 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 is based on similar `clang_CXXMethod` implementations, returning a falsy unsigned value when the cursor is not a declaration, is not a declaration for a constructor or conversion function or is not a relevant declaration that was marked with the `explicit` specifier. The new symbol was 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, "(explicit)", for cursors that are recognized by `clang_CXXMethod_isExplicit`. Two new regression files, "explicit-constructor.cpp" and "explicit-conversion-function.cpp", were added to "clang/test/Index", to ensure that the behavior of the new function is correct for constructors and conversion functions, respectively. The "get-cursor.cpp", "index-file.cpp" and "recursive-cxx-member-calls.cpp" regression files in "clang/test/Index" were updated as they were affected by the new "(explicit)" tag. A binding for the new function was added to libclang's python's bindings, in "clang/bindings/python/clang/cindex.py", as the "is_explicit_method" method under `Cursor`. An accompanying test was added to "clang/bindings/python/tests/cindex/test_cursor.py", mimicking the regression tests for the C side. The current release note for Clang, "clang/docs/ReleaseNotes.rst" was modified to report the new addition under the "libclang" section.
