Allow protocol relative URLs in CssLink Transformer

Browse Source 
This commit allows the use of "protcol relative URLs" (i.e. URLs without
scheme, starting with `//`), often used to serve resources automatically
from https or http with third party domains.

This syntax is allowed by RFC 3986.

Issue: SPR-12632
