HAVE_WEBP: 

It is defined in PlatformHave.h for Apple ports

#if PLATFORM(COCOA)
#define HAVE_WEBP 1
#endif

USE_WEBP:

It is defined in Source/cmake/OptionsPlayStation.cmake and Source/cmake/OptionsWinCairo.cmake for WinCairo 
And it is defined in PlatformUse.h for GTK and WPE

#if PLATFORM(GTK) || PLATFORM(WPE)
#define USE_WEBP 1
#endif

HAVE_AVIF:

It is defined in PlatformHave.h for Apple ports. See https://github.com/WebKit/WebKit/pull/1717

USE_AVIF:

It is defined in Source/cmake/OptionsWPE.cmake for WPE
And it is defined Source/cmake/OptionsGTK.cmake for GTK


We need a single flag for WebP and another flag for AVIF to control when the image format is enabled.
