More flexible Environment Variables in Edge Functions and Middleware

You now have more flexible access and improved limits for environment variables from Edge Functions and Middleware:

• 
  The max environment variable size is now 64KB instead of 5KB, same as Serverless Functions.
  
  
• 
  Other than the reserved names, there are no additional restrictions to name environment variables.
  
  
• 
  Accessing process.env is no longer restricted to be statically analyzable. This means that, for example, you can now compute variable names such as process.env[`${PREFIX}_SECRET`].
