When I split Qt::partial_ordering off of QPartialOrdering, O
duplicated the partialOrdering() test, but lost the conversion() part
of the tests.
This patch brings them back.
Because we maintained the test coverage for Qt::partial_ordering, it
suffices to check that QPartialOrdering::X correctly maps to
std::partial_ordering::x. The rest follows from transtivity of
equality.
We're still lacking conversions of QPartialOrdering to Qt::_ordering

These macros should unwrap into a proper set of equality and ordering
operators, depending on the C++ standard being used.
For C++17, all 6 operators (==, !=, <, >, <=, >=) are overloaded, while
for C++20 only the overloads for opeartor==() and operator<=>() are
provided.
The macros are documented as internal for now.
The macros rely on two helper functions:
bool comparesEqual(LeftType lhs, RightType rhs);
ReturnType compareThreeWay(LeftType lhs, RightType rhs);
The comparesEqual() helper function is used to implement operator==()
and operator!=().
The compareThreeWay() helper function is used to implement the four
relational operators in C++17, or operator<=>() in C++20.
ReturnType must be one of Qt::{partial,weak,strong}_ordering.
When possible, the functions should also be declared constexpr and
noexcept.
It's the user's responsibility to provide the functions before
using the macros.
Implement a test case which applies the new macros to the dummy
classes, and uses the new helper function to verify the comparison
results.

When using the cosmetic stroker (i.e. plain pens with effective line
width of 1), drawing points with fractional coordinates >= 0.5 would
fill the wrong pixel.
This is a long-standing bug where the drawPoints() code in the
cosmetic stroker code was missed during the painting coordinate system
shift for Qt 5.0. Prior to that, coordinates were interpreted as the
upper left corner of a pixel, so rounding fractional coordinates to
the closest integer would be the correct way to determine the pixel to
be filled. From Qt 5 onwards however, coordinates instead designate
the center point of the primitive to be stroked. In order to determine
which pixel is most covered by the unit square centered in the given
coordinates, fractional coordinates must be rounded downwards
(floored).
This fix makes the behavior consistent between the cosmetic and
non-cosmetic stroker, so that drawPoints() with e.g. penwidths 1 and
1.01 in practice fills the same pixels.

we're no longer bound to copy its API for consistency.
So copy std::*_ordering type API for consistency instead, to ease
porting for users that can already use C++20 and everyone else come
Qt 7.
This patch is another step in that direction, renaming classes and
their memmbers to std-compatible names. QPartialOrdering cannot
change, as it's pre-existing. So add a completely new type
Qt::partial_ordering.
Adding conversions from QPartialOrdering is left for a follow-up
patch.
As a drive-by, change `\c Less` to `\l Less` in the \class
documentation blocks of the new classes.
Amending c6fe64b17c, which didn't have a
ChangeLog:
[ChangeLog][QtCore] Added Qt::{partial,weak,strong}_ordering as
drop-in C++17 stand-ins for C++20's std::{partial,weak,strong}_ordering.
