examples/: compile with QT_NO_CONTEXTLESS_CONNECT
Examples are usually a good way to get to know a new codebase, do not
teach developers who are new to Qt about the 3-arg connect() to begin
with.
Drive-by changes:
- `this` can't be implicitly captured with [=] in a lambda, instead
capture by reference
- Update docs related to the sqlbrowser example; the overloaded signal
it mentions has been removed in Qt6
- In the sqlbrowser example, rename addConnection() (no-arg) overload to
openNewConnectionDialog, suggested in code review
