AX: accessibility/clip-path-bounding-box.html fails in macOS Tahoe because
AccessibilityNodeObject and AccessibilityRenderObject don't explicitly enforce
a minimum size for controls

Reviewed by Joshua Hoffman.
With this commit, we now enforce a minimum size for controls for main-thread
accessibility objects (matching the same
change done for AXIsolatedObjects some time ago), ensuring the rects we return
are large enough for assistive technologies
to draw a cursor for. This is helpful for low-vision users who rely on
magnifying the cursor contents — having no cursor
(as happens for 1x1px elements in ATs like VoiceOver) can be disorienting,
especially for interactive elements like controls.
Fixes accessibility/clip-path-bounding-box.html for macOS Tahoe. We used to
implicitly get this behavior, but no longer
do after the controls redesign in Tahoe, so this commit makes it explicit to
fix the test. This logic, which was in
AXIsolatedObject, is now moved to the WebAccessibilityObjectWrapperMac so both
object subclasses benefit from it.
