Christoph Neuhauser 91e83d94c5 Fix: Tests: Pass noise dependent EEVEE render tests on Intel GPUs
This PR slightly raises the accepted noise level for the following EEVEE
tests that were likely incorrectly marked as failed on Intel GPUs:
- render_layer: aov_transparency
- light: triangle_light_sampling
- bsdf: metallic_thinfilm_physical, metallic_thinfilm_f82
- principled_bsdf: principled_bsdf_transmission
