Enable scriptable render pipeline support for Blink Teleport Provider

[FejZa]

XRTK - Mixed Reality Toolkit Pull Request

Overview

I need the blink teleport provider to support scriptable render pipelines. In the legacy pipeline it was possible to change a materials properties to support transparency at runtime. With render pipelines this is not possible anymore for performance reasons (they said). So I made the material used for blinking a configurable setting in the provider's profile, which is useful in many ways anyways. Also exposed two more settings that were hardwired in the provider previously.

Changes

• Exposed fade material and colors as settings in the blink teleport provider profile
