[NaCl SDK] Beginnings of moving more stuff from build_sdk.py to GYP.

Adds a new target to all.gyp: chromium_builder_nacl_sdk
Adds a native_client_sdk gyp file: it depends on nacl_core_sdk from the native_client repo, but also builds and copies ppapi libraries to the toolchain directories.

BUG=none
