[Android] Auto-generate RTL layout xmls from existing layout xmls.

    
    There are several attributes introduced in API 17, mostly for BiDi(RTL) support, e.g., paddingStart.
    This build script will generate another set of resource that is API 14 compatible by
    converting those API 17 attributes to API 14 attributes, e.g., paddingStart -> paddingLeft.
    The goal of this script is for programmers to use those attributes without worrying
    about backward-compatibility care and related bugs. About the bugs, please refer to crbug.com/235118 .
