art: Refactor RuntimeOptions/ParsedOptions
Refactor the RuntimeOptions to be a
type-safe map (VariantMap, see runtime_options.h) and the ParsedOptions
to delegate the parsing to CmdlineParser (see cmdline/cmdline_parser.h).
This is the start of a command line parsing refactor, and may include
more in the future (dex2oat, patchoat, etc).
For more details of the command line parsing generator usage see cmdline/README.md
