  Log Message:
  -----------
  ANGLE mtl_render_utils.h various classes have uninitialised std::array<> members

Reviewed by Dean Jackson.

Initialize all needed std::array<>s via value initialization.
The default initialization does not initialize the array, leading to
uninitialized reads.

The std::array<>s in RenderUtils are value-initialized in the constructor.
