qmljs: added qmljsconstants.h

Moved Document::Language, Import::Type and StaticAnalysis::Severity
enums to qmljsconstants.h and renamed values removing the redundant
part.
Thus the effective length changed little or improved
(Document::QmlLanguage => Language::Qml).

The separate file allows better reuse of enum values without introducing
circular dependencies.
