Add configuration for async pipeline creation on RenderPlugin (#11847)

Browse source 
# Objective

Fixes #11846

## Solution

Add a `synchronous_pipeline_compilation ` field to `RenderPlugin`,
defaulting to `false`.

Most of the diff is whitespace.

## Changelog

Added `synchronous_pipeline_compilation ` to `RenderPlugin` for
disabling async pipeline creation.

## Migration Guide

TODO: consider combining this with the guide for #11846

`RenderPlugin` has a new `synchronous_pipeline_compilation ` property.
The default value is `false`. Set this to `true` if you want to retain
the previous synchronous behavior.
