[HttpFoundation] Generate url-safe hashes for signed urls

Generate url-safe signed urls since some clients can't handle parameter encoding correctly and are sending `%2B` as `+` which PHP reads as ` ` (space), making the signature invalid.

Backwards-compatibility is included, and planned to be removed in 8.0 – which will mean all signed urls generated with <7.3 are rendered invalid.
