Reviewed by Brent Fulgham.

IOMasterPort is deprecated, but still used up until Big Sur, so let's
add a check for IOMainPort and then use it if the OS has it.

Additionally, there is an unnecessary retain + release before
IOServiceOpen, so let's remove that.

*Source/WTF/wtf/PlatformHave.h: Add check for IOMainPort
*Source/WebCore/platform/graphics/mac/GraphicsChecksMac.cpp: Rename
masterPort to mainPort and remove pointless initialization. Also remove
unneeded IOObjectRetain and IOObjectRelease calls in the same exact
codepath. Replace calls from IOMasterPort to IOMainPort
*Tools/DumpRenderTree/mac/LayoutTestHelper.m: Rename masterPort to
mainPort. Replace calls from IOMasterPort to IOMainPort
