[TextureMapper] Do texture transformation in vertex shader when copying
texture
https://bugs.webkit.org/show_bug.cgi?id=261187
Reviewed by Fujii Hironori.
With the current implementation, transformation of texture coordinate
is performed in a fragment shader when copying texture or applying blur.
This change will move the transformation to vertex shader for better
performance.
