[clang-format] Always indent wrapped Objective-C selector names

Summary:
Currently, indentation of Objective-C method names which are wrapped
onto the next line due to a long return type is controlled by the
style option `IndentWrappedFunctionNames`.

This diff changes the behavior so we always indent wrapped Objective-C
selector names.

NOTE: I partially reverted https://github.com/llvm-mirror/clang/commit/6159c0fbd1876c7f5f984b4830c664cc78f16e2e / rL242484, as it was causing wrapped selectors to be double-indented. Its tests in FormatTestObjC.cpp still pass.

Test Plan: Tests updated. Ran tests with:
  % make -j12 FormatTests && ./tools/clang/unittests/Format/FormatTests
