testlib: Introduce MouseDoubleClickSequence() method

The existing method MouseDoubleClick() emulates the mouse
double click event only.

The added method MouseDoubleClickSequence() emulates the full
sequence of mouse events a physical double-click would generate:
Press-Release-Press-DoubleClick-Release

Introducing a new method in order to provide convenience when a
test requires to simulate a complete double-click action without
changing the behavior of MouseDoubleClick() and risking to break
existing tests.

Add autotest.
