Add a bounding box intersection test to QgsGeometry
...
We only previously had methods for exact intersections - this
commit adds a new QgsGeometry.boundingBoxIntersects() method
which can be used to test if just the bounding boxes of
geometries/rectangles intersect.
It's fast, and doesn't care about invalid geometries (unlike
the exact intersects checks)

Provide an optimised constructor for a null QgsRectangle

This is used a lot, yet the current constructor calls the
normalize() method which does a bunch of operations for no
result.
So instead provide a simple optimised null QgsRectangle

Refine behavior of QgsGeometry equals tests
...
Before we had two checks - equals() and isGeosEqual() which
performed the exact same check (since equals() called the geos
equality test)
Since the geos equality test is a slow, topological test, which
considers two geometries equal if their component edges overlap,
but disregards ordering of vertices this is not always what we
want. There's also the issue that geos cannot consider m values
when testing the geometries, so two geometries with different
m values would be reported equal.
So, now calling QgsGeometry::equals performs a very fast, strict
equality test where geometries are only equal if the have exactly
the same vertices, type, and order.
And swap most code which was calling the slow geos test to instead
use the fast strict native test.
