[clang-format] Set IndentWrappedObjCMethodNames to Always in google style

[benhamilton]

Summary

Now that we can separately control ObjC method name wrapping
and non-ObjC function name wrapping, this diff sets
IndentWrappedObjCMethodNames to Always for the Google style.

Depends On D45004

Test Plan: Updated test which manually set
IndentWrappedFunctionNames to no longer set that, confirmed
tests which depended on indenting wrapped ObjC method names
still passed.

[benhamilton]

Abandoned in favor of unconditionally indenting wrapped ObjC selectors in D45004.
