Eevee Bevel shader node

The original bevel node unfortunately doesn't work in Eevee, so I make my own version!

It gives pretty good results even with few geometry or bad topology due to boolean operations.

PROS:

• add a procedural bevel to get a more realistic look
• it'll not generate additional geometry
• it works even with a bad topology where a bevel modifier is impossible to apply

CONS:

• with a really bad topology there could be some imperfections (I'll make a better version with the 3.5 blender version)
