Exclude Save-Data from CORS Access-Control-Request-Headers

Exclude Save-Data from CORS Access-Control-Request-Headers

When data saver is enabled, and a cross-origin fetch by a webpage is
intercepted by a serviceworker and the serviceworker does a fetch, the
preflight request will have save-data added to
Access-Control-Request-Headers. As a short-term fix save-data will be
excluded from ACRH header.

Later all simple headers will be excluded from ACRH header.
