Fix markdown headings

GitHub recently changed how atx headings (beginning with `#`) are
rendered. A space is now required between `#` and the following text
for the heading to be recognized.

Update headings in the docs to match the expected format.

 # CoreClr Event Logging Design
 
-##Introduction
+## Introduction
 
 Event Logging is a mechanism by which CoreClr can provide a variety of information on it's state. This Logging works by inserting explicit logging calls by the developer within the VM . The Event Logging mechanism is largely based on [ETW- Event Tracing For Windows](https://msdn.microsoft.com/en-us/library/windows/desktop/bb968803(v=vs.85).aspx)

 # .NET Cross-Plat Performance and Eventing Design
 
-##Introduction
+## Introduction
 
 As we bring up CoreCLR on the Linux and OS X platforms, it’s important that we determine how we’ll measure and analyze performance on these platforms.  On Windows we use an event based model that depends on ETW, and we have a good amount of tooling that builds on this approach.  Ideally, we can extend this model to Linux and OS X and re-use much of the Windows tooling.
