[WPE][GTK] Skia compositor blends opaque contents buffers, wasting memory
bandwidth
https://bugs.webkit.org/show_bug.cgi?id=320745
Reviewed by Carlos Garcia Campos and Nikolas Zimmermann.
m_contentsOpaque only describes what the layer paints into its own tiles,
so a
layer whose contents come from an opaque buffer like a WebGL canvas created
with
alpha:false, an opaque video frame or an opaque image, are composited with
source-over and read the destination for every pixel adding read bandwidth
usage.
TextureMapper gets the same decision off the buffer flags.
Consider those flags too, restricted to layers with no backing store of
their
own, since the flag says nothing about the opacity of the layer's own tiles.

[WPE][GTK] REGRESSION(318402@main): canvas and image layer contents
composited without blending
https://bugs.webkit.org/show_bug.cgi?id=320895
Reviewed by Carlos Garcia Campos.
Since 318402@main the Skia compositor decides whether a layer's contents
buffer needs blending from the buffer's TextureMapperFlags::ShouldBlend
flag. CoordinatedPlatformLayerBufferSkiaImage, the buffer type used for
accelerated 2D canvas contents and image backing stores on the Skia
compositor path, never set that flag. Set ShouldBlend from the SkImage
opacity when creating the buffer.

[CMake][WPE] Remove "find_package(Unifdef REQUIRED)" from OptionsWPE.cmake
https://bugs.webkit.org/show_bug.cgi?id=320985
Reviewed by Adrian Perez de Castro.
Even with USE_SYSTEM_UNIFDEF=0, WPE builds failed due to the missing system
`unifdef` command. 283695@main added the USE_SYSTEM_UNIFDEF option, and
moved
"find_package(Unifdef REQUIRED)" from OptionsGTK.cmake to
Source/CMakeLists.txt. Removed it from OptionsWPE.cmake too.
