[bazel] Move CanvasKit configuration options to buildrc

Removing cc_binary_with_flags will make it easier to have
more compiled options (e.g. CPU only build) and conforms
with how we plan to have options.

The supported build configurations will live in buildrc
as sets of flags to turn things on or off.
