BLI_math: unify zero area checks for barycentric weight calculation

This applies the change from T73348 fix to related functions.

Instead of checking against an epsilon to avoid divide by zero,
perform the division and check the result is finite.

This is needed since small faces can have an area under 'FLT_EPSILON',
and dividing by values close to zero can result in 'inf'.

GPU: Fix huge performance regression regarding instancing

Under some circumstances, MultiDrawIndirect was disabled to improve perf.
of average scene. But this conflicted with the normal instancing buffer
filling if only 1 or 2 instances were needed to fill the buffer. All
consecutive drawcalls could not be batched together and performance would
degrade rapidly.

This patch make my instance test scene go from 11fps back to 40fps where
it should have been.
