dockstore-ui2 pipes that call functions

Description This draft PR explores a technique that harnesses Angular pipes and associated change detection infrastructure to efficiently call functions from our Angular templates.

This PR creates two pipes: function, and method.

The function pipe binds its first argument as this to its second argument, which is a function. The bound function is then called, with the first argument being the pipe input value, and the remaining pipe arguments being the additional function arguments. For example, the Angular expression {{ org | function: this:brace }} maps to the function call this.brace(org)

The method pipe binds the pipe input value as this to its first argument, which is a function. The bound function is then called, with the remaining pipe arguments. For example, the Angular expression {{ org | method: org.getLink }} maps to the method call org.getLink(). A more advanced implementation would also support a string as the first argument, which would name a field of the piped value, and get eval-ed to a function value at run time.

All the example invocations in the PR don't do anything useful at present, and two are broken.

This is a very rough proof-of-concept, not production ready, and should not be merged.
