TextureMapper: Calculate zFar and zNear for the projection matrix
https://bugs.webkit.org/show_bug.cgi?id=244564
Reviewed by Darin Adler.
TextureMapper was using fixed zFar and zNear values, (-99999,
9999999). These were too big for 16 bits depth buffer on Linux.
<https://bugs.webkit.org/show_bug.cgi?id=244526#c2>
Changed TextureMapperLayer::computeTransformsRecursive to calculate
zFar and zNear.
