Make GraphicsLayerTextureMapper code platform agnostic
https://bugs.webkit.org/show_bug.cgi?id=246497

Reviewed by Fujii Hironori.

Replaces `PLATFORM(WIN)` code with checks for
`USE(GRAPHICS_LAYER_TEXTURE_MAPPER)` or `USE(GRAPHICS_LAYER_WC)` where
applicable. Modify types to platform specific ones. The patch largely
modifies code from 225218@main to be port agnostic.

nativeWindowHandle is not only for GraphicsLayerTextureMapper, but also for GraphicsLayerWC. And, I have a plan to remove GraphicsLayerTextureMapper after removing WinCairo WK1 and migrating Microsoft Playwright to GraphicsLayerWC.
I think it should be #if USE(GRAPHICS_LAYER_TEXTURE_MAPPER) || USE(GRAPHICS_LAYER_WC).
