Some WebIDL operations / attributes incorrectly use _current_ realm instead of _relevant_

Source/WebCore: This patch replaces _current_ global object with _relevant_, as per recommendation for spec authors [1], for select WebIDL operations / attributes that satisfy all the following conditions: 1) it's an instance member: static ones and constructors can't use _relevant_; 2) it's on standards track (not deprecated / WebKit-only / internal); 3) the change is directly observable: global object is used for something beyond lifecycle / event loop / parsing CSS etc; 4) the change either aligns WebKit with both Blink and Gecko, or the spec explicitly requires _relevant_ realm / settings object. Most of the remaining [CallWith=GlobalObject] instances are correctly used for converting JS arguments to WebIDL values; the rest, along with _current_ Document and ScriptExecutionContext, either match the spec or replacing them with _relevant_ global object is not directly observable (see condition #3). This change is aimed at fixing web-exposed APIs rather than performing a global cleanup.
