[GTK][WPE] Skia Compositor: Make *ForChildren transforms transient
https://bugs.webkit.org/show_bug.cgi?id=313307
Reviewed by Carlos Garcia Campos.
The combinedForChildren and futureCombinedForChildren matrices on
SkiaCompositingLayer::m_transforms are only consumed by the parent's
recursive call into each child within computeTransformsAndAnimations.
no paint-time site reads them. Storing them in m_transforms causes
confusion because both are actually transient.
Drop both fields from m_transforms and pass them as parameters to the
recursive call instead. Also drop the parent parameter and hoist
parent == m_parent decision into each caller.
