Substance Painter : add settings to filter Output Template for publishing

When publishing from Substance Painter, the gui asks to choose the Output Template among a list which is too long : the 35 standard Substance templates.

Artists can too easily choose the bad one, or take too much time finding the right one.

So, it would be nice to have in Studio Settings a way to declare a few Output Templates for Substance, so for example the artist would only have to choose between the ones allowed by the studio.

Example :

• PBR Metallic Roughness

• Unity Universal Render Pipeline (Metallic Standard)

• Unreal Engine 4 (Packed)
