Allow using #import directive for C++ headers in ios/ directory.

The following text was added to Chromium Objective-C and Objective-C++
style guide:


all source code in ios/ directory. This differs from Google Objective-C
Style Guide, which requires using #include directive for C++ headers.


The usage of #include and #import is inconsistent for the same headers
and cause a lot of frictions during the code reviews. The proposal to
run PRESUBMIT script which fixes #include/#import usage was rejected
due to performance reasosn, so relaxing style guide is the only option
to simplify codereview process.

Original attempt to add presubmit script was here:
