Extend semantic highlighting token types

Currently, semantic highlighting provides token information coarsely than the embedded code model highligher in Qt Creator. We need more fine grained token information to reach feature parity with Qt Creator.

Make sure that introducing new token types shouldn't break the other text editor's interpretation of the token data. You should get this from the client capability.

Consider the following labels in QtCreator:

QML Binding

Qml Local Id

Qml Root Object Property ?? What is this?

Qml Scope Object Property ?? What is this?

Qml State name

Qml Type name

Qml External Id

Qml External Object Property

JavaScript Scope Var

JavaScript Import

JavaScript Global Variable

Punctuation
