mac: Simplify sdk_forward_declarations.h

MAC_OS_X_VERSION_MIN_REQUIRED corresponds to -mmacosx-version-min, which
we currently set to 10.7 (and plan to set to 10.9 eventually, after fixing
deprecation warnings).

MAC_OS_X_VERSION_MAX_ALLOWED corresponds to the SDK used to compile
chrome.  We currently require the 10.10 SDK.

Remove all code in sdk_forward_declarations that's no longer necessary.
No behavior change.
