QQmlSA: Create an abstraction layer for static analysis

This patch adds abstractions for QML Elements, Bindings, Methods and
Properties. This abstraction layer avoids exposing internal details and
should be more suited for static analysis tasks. It is now possible to
write qmllint plugins without including private headers.

As a drive-by, change tst_qmllint:verifyJsRoot to open files in text
mode instead of binary. This fixes an issue where line endings cause
issues on Windows.

Fixes: QTBUG-102276
