LibWeb: Send appropriate Accept header for FrameLoader requests

Browse source 
According to Fetch, we must send an Accept header with the value
"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
for document, iframe and frame requests.

// Step 12: If request’s header list does not contain `Accept`, then:
// 1. Let value be `*/*`. (NOTE: Not necessary as we're about to override it)
// 2. A user agent should set value to the first matching statement, if any, switching on request’s destination:
// -> "document"
// -> "frame"
// -> "iframe"
// `text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8`
// FIXME: This should be case-insensitive.
