Merge the sampler uniform application into ProgramBinary::setUniform.

 * Fixes incorrect dirty checks for the dirty sampler mappings flag.
 * Fixes WebGL tests:
   * conformance_canvas_texture_bindings_unaffected_on_resize
   * conformance_reading_read_pixels_test
   * conformance_uniforms_uniform_default_values
