GrMatrixEffect applies coord normalization/flip for GrTextureEffect.

It checks if its child is a GrTextureEffect and if so the child supplies
a matrix to concat.

Additionally, GrTextureEffect shader modes that operate on unnormalized
texture coords no longer receive prenormalized coords that must be
unnormalized.

Hoping this addresses (maybe partially) this regression:
