Create top-level ios/public/ directory.

To better mirror the structure of other API layers (content/public and
third_party/WebKit/public), there will be a single ios/public/ directory that
contains all interfaces referenced by not-yet-upstreamed Chrome for iOS code,
rather than these interfaces being scattered in subdirectories further
underneath ios/.

This CL also changes gyp structure to better match other modules: ios_consumer.gyp is moved to directly under ios/, and an ios.gyp is created with a single top-level "ios" target to be used in build/all.gyp.
