a11y: Remove a ### Qt6 that doesn't make much sense
Since the enum names are "the same", the comment seems to suggest to
change the enum value of Canvas to 0x401. I don't see any benefit to
that really.
In addition, we are today using UIA in favor of MSAA, and the closest
matching role (controlTypeId) seems to be for a static image
(UIA_ImageControlTypeId), which is quite different from the semantic of
IA2_ROLE_CANVAS.
For the record, here's a list of similar roles for different a11y APIs:
IA2:
IA2_ROLE_CANVAS An object that can be drawn into and to manage
events from the objects drawn into it. Also
refer to IA2_ROLE_FRAME, IA2_ROLE_GLASS_PANE,
and IA2_ROLE_LAYERED_PANE.
MSAA:
ROLE_SYSTEM_DIAGRAM The object represents a graphical image that is
used to diagram data.
UIA:
UIA_ImageControlTypeId Identifies the _Image_ control type.
atspi:
ATSPI_ROLE_CANVAS Object that can be drawn into and is used to
trap events.
