Update Cube texture.
@attention It’s valid to update only mutable texture. See bgfx::createTextureCube for more info.
@param[in] _handle Texture handle.
@param[in] _layer Layer in texture array.
@param[in] _side Cubemap side BGFX_CUBE_MAP_<POSITIVE or NEGATIVE>_<X, Y or Z>,
where 0 is +X, 1 is -X, 2 is +Y, 3 is -Y, 4 is +Z, and 5 is -Z.

@param[in] _mip Mip level.
@param[in] _x X offset in texture.
@param[in] _y Y offset in texture.
@param[in] _width Width of texture block.
@param[in] _height Height of texture block.
@param[in] _mem Texture update data.
@param[in] _pitch Pitch of input image (bytes). When _pitch is set to
UINT16_MAX, it will be calculated internally based on _width.
