##Fixes:
Make adaptive expression library compatible with IE

Description

There was no support of IE in the adaptive expression library. Using babel to transpile compiled code and add polyfills so that it works in IE also.

Specific Changes

• Using babel to transpile adaptive-expression and other dependent libraries which are not compatible with IE.
• Adding core js to resolve all polyfills which are used in those dependent libraries.
• Updated templating library package json to create a webpack build in dist folder which is compatible with IE

Testing

Tested manually by taking dependecy in adaptive card designer in IE to make sure that there are no errors

One small comment, can you verify that this bundle still works for your use case as well?

Yes, I did verify it with adaptive-designer. I had to add aliases for the same but it worked. These are the 3 changes I did :

1. package json, I removed the expression dependency and added dependency for ie 11 :
   
2. Added alias in webpack:
   
3. Added alias in tsconfig:

Thanks. Can we merge this ?

Is there any benefit to us including "src"? If someone wanted to use the "src", they should likely instead use adaptive-expressions, right?

Yes, thanks for pushing those changes
