Corentin Wallez ec9cf2a85c Rename namespace dawn_native to dawn::native.
But keep a namespace alias to avoid breaking project that depend on the
previous namespace name while they get updated.

Done with through the following steps:

 - git grep -l dawn_native:: | xargs sed -i "" "s/dawn_native::/dawn::native::/g"
 - git grep -l "namespace dawn_native" | xargs sed -i "" "s/namespace dawn_native/namespace dawn::native/g"
 - git cl format
 - Manual fixups in generator/templates (and the addition of
   namespace_case in dawn_json_generator.py).
 - The addition of the namespace alias in DawnNative.h
