[Graphics, Particles] Normals and Tangents in Particle System are incorrect with specific particle settings

Shuriken

-

How to reproduce:
1. Open attached project "Normals.zip" and scene "NormalBugTest"
2. Observe all the objects

Expected and actual results:
Object #1 (ParticleSystem_Billboard_LocalAlignment_NormalBug#1)
Incorrect normal

Object #2 (ParticleSystem_StretchedBillboard_NormalTangentBug#2)
Tangent is correct, incorrect normal

Object #3 (ParticleSystem_Billboard_LocalAlignment_Flip_NormalTangentBug#3)
Tanget is not flipped(is not correct)

Object #4 (ParticleSystem_MeshSphere_ShapeScale_NormalTangentBug#4)
Incorrect tangent and normal

Object #5 (ParticleSystem_MeshSphere_TransformScale_NormalTangentBug#5)
Incorrect tangent, correct normal

Reproducible with: 2018.4.8f1, 2019.2.4f1, 2019.3.0b2, 2020.1.0a2
Could not test with 2017.4 (errors are thrown, the used Shader requires LWRP package but LWRP is unrelated to the particle bugs)
