Uniform: use QVarLengthArray<16 ,float> instead of <4, float>
This otherwise yield for lots of reallocations that could be avoided.
The gains seem to be about 2/3% of cpu usage according the analysis
with vTune.
It does indeed mean that for smaller uniforms vec4, float, sampler
we are wasting a bit of memory. The impact of this is likely to be
unsignificant though.
