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`.

For the Google style, we'd like to indent Objective-C method names
when wrapped onto the next line, but *not* indent non-Objective-C
functions when wrapped onto the next line.

This diff adds a new style option, `IndentWrappedObjCMethodNames`,
with three options:

1. Auto: Keep current behavior (indent ObjC methods according to

`IndentWrappedFunctionNames`)

2. Always: Always indent wrapped ObjC methods

3. Never: Never indent wrapped ObjC methods

In a separate diff, I'll update the Google style to set
`IndentWrappedFunctionNames` to `Always`.

Test Plan: Tests updated. Ran tests with:

  % make -j12 FormatTests && ./tools/clang/unittests/Format/FormatTests
