Non-SFI mode: Implement test launcher for nacl_helper_nonsfi_unittests.

This CL implements a test launcher customized for nacl_helper_nonsfi_unittests.
- Existing nacl_helper_nonsfi_unittests is renamed to nacl_helper_nonsfi_unittests_main.
- The new test launcher is built with a toolchain for the target architecture rather than PNaCl toolchain.
- XmlUnitTestResultPrinter is now extracted into a separate file.

TEST=Ran bots (with and without editing testing/buildbots scripts). Run locally.
BUG=358465
