Limit GL_TEXTURE_RECTANGLE filtering to bilinear.

Adds a clamp for GrTexture filtering that can be set by a subclass at construction. The clamping is performed by GrTextureParams. GrGLTexture limits filtering to bilinear for rectangle and external textures.

Also moves samplerType() to GrTexturePriv from GrTexture.
